Michael Bublé - Don't Take Your Love From Me (arranged by Callum Au)
– full of invention, talent, virtuosity, passion and an overwhelming feeling that a large collective of musicians were all in absolute unison and enjoying every minute of it… as indeed every listener should, as well.

Au clearly possesses his own 24-carat storytelling gift.
Callum Au is an extraordinarily gifted musician. His ability to write and arrange with such sensitivity and depth of emotion is breathtaking and his knowledge base is wide, sophisticated and deeply impressive. Callum understands and respects lyrics and always beautifully frames singers to let them shine. What a joy to work with him and to witness his star ascending.

…the remarkable young arranger Callum Au is already a master [of the] mysterious art of orchestration and arranging.
Over the past six years, Callum Au has become my most trusted musical collaborator. A musician’s musician, he is the consummate arranger/orchestrator who can take any idea and run with it — never ceasing to amaze! In an era short on Nelson Riddles, Callum remains peerless — filling this void with his own remarkable style, taste and musicality.
These are the songs and stories you are unlikely to ever tire of listening to. Callum Au, with his bright, scintillating arrangements has achieved the near impossible, turning 11 sturdy but well-worn standards into fresh music.
Callum is an astonishingly gifted musician. He is able to produce world-class arranging for any ensemble at lightning speed. I have in the past commissioned him at 10.30 in the morning or thereabouts and had a set of parts beautifully copied out by the start of the bandcall at 4 on the same day. Similar standards apply to his trombone playing. A seemingly effortless technique is backed up by flawless reading and ear playing. Best of all, he’s a really generous musician, who revels in developing the skills of those around him. And he knows a lot about food.

This album [Songs And Stories] is a glorious thing, with incredible instrumental and vocal performances. Filled with beautifully balanced and nuanced orchestrations, as a fellow orchestrator, I am full of admiration for Callum Au.
