Greg Tuohey was born in Auckland, New Zealand. He began playing music at the age of 5 as a classical pianist but switched to guitar at 10 years old. By the age of 15, Tuohey was playing professionally in jazz clubs across Auckland, earning a name for himself as one of the preeminent jazz musicians to emerge from the country.
In 1994 Tuohey was awarded a scholarship to study at Berklee School of Music where he studied for a year before moving to New York. Over the next five years, Tuohey performed and recorded with Mark Turner, Seamus Blake, Reid Anderson, Ari Hoenig, George Garzone and many others. He was a founding member of the collaborative jazz group "Flipside" with Matt Penman, Darren Beckett and Jerome Sabbagh. "Flipside" released their debut album on Naxos Records in 1998 and toured extensively throughout Europe, the UK, Northern Ireland and New Zealand. In 2000, Tuohey became disillusioned with jazz and improvised music. He picked his last gig and then didn’t play a note of jazz for over a decade. Instead, Tuohey worked strictly in rock music as a session guitarist as well as playing and touring with various rock bands. Notably with critically acclaimed indie-folk singer Joe Pug, with whom he still tours and records with to this day. In 2010, Tuohey began playing improvised music again, an effort culminated in the release of First (2013). First was Tuohey’s first jazz record as a leader, and featured rising young Chicago musicians Dan Pierson, Mike Harmon and Matt Carroll. In 2013 Tuohey returned to the New York music scene, where he maintains a rigorous touring and recording schedule with Joe Pug and other rock acts as well as playing improvised music with Aaron Parks, Orlando Le Fleming, Jerome Sabbagh and many others.
