Phi Life Cypher is a British hip hop group based in Luton, comprising two MCs, Si Phili and Life MC, and DJ Nappa. The trio started making music together around 1996, and since have had much success on the UK underground circuit. Phi-Life Cypher made it to the final of Tim Westwood's Talent 2000 competition and ripping the mic on DJ Skitz's seminal posse cut 'Fingerprints of the Gods' projected them to the upper realms of the UK Hip Hop scene.
Phi Life Cypher released "Clint Eastwood" the track on the Gorillaz' G-Sides, a compilation of the B-sides from the first three singles was released in Japan and quickly followed with international releases in early 2002. The new year also saw a performance at the 2002 Brit Awards, featuring the band in 3D animation, weaving in and out of each other on four large screens along with rap accompaniment by Phi Life Cypher.
