Biography
Sirke 603 was a name for Sirke while performing a special instrumental postrock set in the summer of 1997. The set, radically different from everything else the band was doing at the time, was kept a secret while practising, also from other bands sharing the Tornis studio. It was first performed at the opening gig of Sirke, Bowling Boi and Ray Speedway and the Devils of Pace minitour. Later the band switched to instrumental music only and discarded the Sirke 603 moniker.
