Galkin's compositions were performed by Tim Garland's Northern Underground Orchestra.[3] In the late-2000s, Galkin founded the nine-piece Symbiosis Jazz Orchestra performing his own compositions.[3] In October 2009, the orchestra recorded its first CD, which contained seven of Galkin's original works; it was released by the F-IRE Collective.[4] Galkin's composition "Evolvent" won the 2010 Dankworth Prize for Jazz Composition.[2]
Galkin moved to New York City in 2017.[5] There, he recorded his second album, ...For Its Beauty Alone,[5] which was released in 2019 and featured saxophonist David Binney, pianist Matt Mitchell, and drummer Rudy Royston.[6]
