OSI, the prog rock duo of Jim Matheos and Kevin Moore, are preparing the release of their new album, Fire Make Thunder and are now streaming a new song from the album, the seven minute powerhouse, ‘Cold Call’. With big imposing riffs and Moore’s chilling, eerie singing the song is the usual brooding air that characterises OSI. Have a listen to the song over at Decibel now for a taster of the new record.
