An incredible band from Edinburgh!

"The foundations of the band were laid in late 2002 but education slowed progress until late 2005. Vocalist Mikey then brought together the band, a five piece blend of youth and experience, through the wonders of the internet and Serpico was born as a live act that has begun to leave its mark on the UK gig circuit. Recent gigs have included highly praised support slots for multi-platinum acts such as Paradise Lost in London and a hometown support for US giants AFI, as well as tour supports for established Brit Rockers InMe and up-and-coming stars Lost Alone."
