The respected Sydney musician has died at the age of 28.

Multi-instrumentalist Luke Liang is being mourned by many corners of the Australian music industry today.

A former member of Sydney band Papa vs Pretty, Liang was well known around the country for work with Alex the Astronaut, M-PHAZES, Jack River, Ruel, The Aston Shuffle and Guy Sebastian.

He was a go-to session musician in the eyes of many creatives looking for talented flair to be brought to their sessions, recordings and live performances for instance, for visits to the Like A Version studio.

In a statement on Facebook today, Liang's former Papa vs Pretty bandmate (and current Jack River guitarist) Tom Myers remembered Luke as a funny and wickedly talented musician.

"Luke officially joined Papa vs Pretty just before the writing and recording of our second album." he wrote.

"He was intimidatingly amazing at his instrument and made our music stand out. I can still hear his playing on it today and its just as masterful."

"After the band broke up, Luke became the absolute "go-to" session guy. Quite simply, he was the best. Keys/Guitar/every other instrument, If you were lucky enough to see Luke play, you'll understand. My heart aches for all who shared the stage with him, I'll bet they were the best gigs you've ever played. Luke was perhaps the most impressive man I've ever met. Literally anything he turned his hand to he mastered (sometimes in a matter of hours), a willing listener and an incredible mate to all of us."

Friends of Luke's and industry are encouraging those affected to reach out to Support Act - the national charity that has been established to help Australian artists and music workers who are facing difficult times due to mental health problems, illness or crisis.
