Session Musicians (Orchestral Contracting and String Sections) 

Concerts/Tours and TV


…phenomenal musicians

…all so damn good-looking!

Harry Connick Jr.

This orchestra is… dare I say it… Amazing! – A brilliant, brilliant orchestra – Truly wonderful.

Michael Bolton

I can’t recommend Leah highly enough.

She has fixed several orchestras for me over the last few years and on every occasion has come up with exactly what is required, and on budget.

Baz Archer – The Music House

Leah wrangled a 43 piece all-female orchestra for me in 2008. We called it ‘Symphonie des Femmes’ and they played at the State Theatre with The Whitlams. I didn’t know there were so many beautiful musicians in Sydney.

They sounded great and Leah was a dream to work with.

She is a very professional operator.

Tim Freedman – The Whitlams

We could always trust you to bring the best of the best music to each show.  You were always reliable and always brought a million percent of your incredible skill to each show. The Voice would certainly not have been what it was without you.

The Music Department – The Voice Australia 

Thanks so much Leah!

It was a real pleasure to work with you and you put together fantastic orchestras for us.

They sounded great and were a lot of fun to share the stage with.

We really appreciate your hard work.

Phil Burton – Human Nature

Leah has contracted musicians for me for several events.

On each occasion she has provided musicians appropriate to the context of the production, who have been both professional and easy to work with.

I would have no hesitation whatsoever in recommending Leah’s services to anyone who requires a competent, creative industry professional who is able to provide the most suitable musicians for exactly the right occasion.

Paul Dellit OAM – Producer, Queensland Performing Arts Centre

I had the great pleasure of working with Leah on our 2010 world tour. Not only did she hire the finest musicians for our TV spots and 6 concerts throughout Australia, she also played solo viola with the band.

Her string sections were well prepared and easy to rehearse. They knew how to swing and were total Pros.

I highly recommend her as a player, a colleague and a contractor.

Leah Zweck/String Source is simply the best!

Sylvia D’Avanzo – Lead Violinist, Harry Connick Jr. Band.

A trip to Australia would not be the same without working with Leah Zweck and the fine musicians she sources.

I have had the pleasure  of working with Leah in her capacity as musician and fixer many times and have always been so impressed by her musicianship and work ethic.

She is a true professional and a pleasure to have on tour.

She makes sure the whole touring party is happy, both on and off the platform.

I look forward to many more happy years of working together.

Aled Jones – Singer/Presenter

An absolute delight and pleasure Leah. You and your musicians are exquisite players and all lovely as well!

Gaynor Crawford – Music Promoter

I can’t tell you how much we appreciate all your help over the last few weeks. You were an enormous help.

Thank you very much for organizing all the players, especially at such short notice. Every single person was amazing and it was a pleasure to have them join us.

Vince Pizzinga – Musical Director, Delta Goodrem

String Source has become a valuable resource for the State Theatre when negotiating with promoters and corporate clients.

Leah brings not only first class musicians and musicianship but also impeccably presented talent.

I will continue to make Leah and String Source our first call when seeking musicians for both public and corporate performances at State Theatre and I regularly encourage many colleagues and clients to do the same.

John Glenn – Former General Manager, State Theatre/Current Director Programming, Queensland Performing Arts Centre

In our experience String Source were thoroughly professional, excellent players.

Overall organisation of musicians covering all cities throughout Belle & Sebastian’s touring in Australia was extremely good.

Highly recommended, particularly for touring bands looking for local / touring professional musicians.

Stephen MacDougall (Stevie Dreads) – Tour Manager, Belle and Sebastian

String Sirens Concerts/Tours


I worked with Leah Zweck and the players from The String Sirens on many occasions – on television, at live events and in the recording studio.

The people in this group are professional, hard-working, easy-going and superb musicians.

John Foreman – Musical Director 

As Glenn’s Musical Director, I could not have wished for a better string quartet than the “String Sirens” to work with.

Their musicianship and dedication to getting it right in rehearsal carried through to every performance.

By tour’s end they even had their own solo spot opening the second act for Glenn with a fantastic Beatles tribute!

They also have the glamorous good looks that light up a stage, captivate an audience and add style and class to any show. They certainly did this for us.

With their electric on stage presence and as professional musicians, I have no hesitation in recommending the “String Sirens” for any musical task – from a string quartet for a garden party through backing rock artists or as section leaders in a full orchestra!

The String Sirens are great!

Stewart Wilkinson – Musical Director, Glenn Shorrock

The String Sirens are both sassy and classy.

They play with passion, they look sensational, and I have been grateful for their work with ‘Bravo’ at StarCity and with ‘Peter Cousens and Friends’ at the Darling Harbour Winter Festival.

Guy Noble – Conductor/Musical Director/Presenter

I programmed the “String Sirens” as part of the “Reminiscing Tour” (starring Glenn Shorrock, Wendy Matthews and Doug Parkinson).

As a featured act, they opened the second half of the show with their Beatles Medley, which had the audience up and dancing in the aisles.

The “String Sirens” not only brought glamour to the show, but also fun and a real positive energy.

Their techno version of Vivaldi’s Summer was also one of the highlights of the “HATS OFF BrizVegas 05” concert that I produced.

Paul Dellit OAM – Producer, Queensland Performing Arts Centre

String Sirens TV

It was FANTASTIC that you could do the Teddy shows and I really can’t thank you guys enough for doing such a great job.

You were all beautiful, sounded brilliant and were a pleasure to be with. All those qualities all bundled together are too rare these days, so thank you.

Rich Sanford – Musical Director - re TV performances with Teddy Geiger

Thanks again for your help. The girls were amazing.

Andrew McLaughlin – National Artist Relations Manager Universal Music Australia - re TV performances with Harrison Craig

It  was such a pleasure to work with you and the girls. I can’t thank you enough for all that you did to make our music so beautiful and bring together such fine musicians.

We have talked about how great you guys were to have around!

Lauren Stamper – Music Coordinator, The Voice Australia

Event Musicians (String and Orchestral Musicians)

Events and Weddings


I can’t thank you enough for the wonderful job you did in pulling together the orchestra for us for the Star Wars Premiere.

It was amazing and you made it all too easy!  Nothing was a problem and I am so glad we found you!

Please pass on my thanks to your conductor and the wonderful musicians you pulled together within a week – so professional and amazing!

Natalie Butler – Executive Producer, Visual Event Management

Thank you Leah! You were all amazing. Thank you so much. It was truly magic.

Rachel Tuffrey – Pronto Productions (re Melbourne Spring Fashion Week Runway 1 Show)

The String Sirens kicked off our executive xmas function in true class and style.

They read the ambience and mood of the crowd beautifully and easily adapted to adverse weather conditions and other hiccups intuitively and without prompting.

They were truly professional, flexible and easy going, not to mention very talented musicians, impressing our VIP’s who are regular concert goers and music aficionados.

The String Sirens understood my needs as a corporate events organiser and were on the mark (and on time!) with everything from correspondence leading up to the event, the performance on the evening and event follow up.

I would recommend them as an asset to any corporate function.

Kerryn Benbow – Special Projects Co-ordinator, SAI Global


Absolutely amazing! Everything was perfect. Thanks so much for listening and helping with all my requests. Everything was incredible. 

Marc, Groom

An enormous THANK YOU for Saturday evening. The quartet was fantastic and loved by the crowd. HUGE THANKS.
