Nick McCarthy was born in Blackpool, England and grew up in Munich, Bavaria, Germany.

He trained classically as a pianist and double bassist at the Munich Conservatory.

Whilst residing in Germany, McCarthy was a member of a band called Kamerakino. He also played double bass, cello and Arabic lute in a band called Embryo, whose music is described as a 'fusion of jazz, rock and ethnic world music.' After extensively touring internationally with Embryo, McCarthy decided it was time for somewhere new, returned to the UK and, on a friend's suggestion, moved to Glasgow.

There, McCarthy broke into Glasgow's underground cultural scene as a member of the jazz band Scatter. Shortly after, he met Alex Kapranos, now of Franz Ferdinand fame.
