The Age described David Cosma as having the "full-bodied croon pairing the silken wryness of Elvis Costello and the gravel of Bob Dylan” while Inpress magazine wrote "a thinking person’s songwriter that speaks volumes to what a terrific talent we have in our midst”.

Inspiring lyrics accompanied by sumptuous melodies and harmonies, together with his unique method of playing the guitar (upside down), guarantees an impassioned live performance. Sonically, his music is rich and luminous and boasts a world class production quality that is often overlooked in the world of independent artists, but it is lyrically where Cosma stands apart, with a knack for examining commonplace and even trite circumstance and then magnifies their significance with a wry and at times ironic tone. Religion, pop culture and nostalgic nuances, punctuate and ultimately, accentuate his writing, triggering instant attention from audience and listeners.
