Formed in Co. Waterford in 2003 by Jim Tobin, Sirocco are a blend of thrashy rythms, beautiful lead guitar melodies, intricate drumming and pounding bass lines, interleaved with plenty of dual guitar harmonies, and old school heavy metal solos, combined to create a sound which they like to call "Celtic Thrash". Originally an instrumental band, bass player Ciaran O' Cearuill stepped up to the mic in early 2007 to finalize the line-up, and is audible on their most recent release "The March Through Crimson Frost", which was officially released in the U.K. and Ireland on April 7th, 2008, through Code7 Music.

Sirocco have played over 60 shows since their inception, including support spots for MEGADETH, WASP, Exodus, SuidAkrA, Firebird, Waylander and Wolfchant, as well as playing at the Cork Winterfest 2007 festival alongside Primordial, The DOD 2008 Festival alongside Watain and the Full Metal Rack 2008 Festival alongside Pagan Altar. The 4-piece have also travelled to the U.K., where they played a headlining show with U.K. metallers Savage Messiah and Heathen Foray in November 2007, and again in June 2008 to headline the inaugural Summer Solstice Pagan Festival. In 2010, they played their first shows in France, Belgium and The Netherlands.

Sirocco are currently writing their third album, which is due for a 2010 release.
