Philadelphia’s SINGLE BULLET THEORY has posted a video featuring guitarist/vocalist Matt DiFabio detailing the epic shredder's free-for-all, 'Auctioneer Of Souls'. The song features solos from DiFabio, new SBT guitarist John Ruszin and a laundry list of metal's most talented six-stringers, including Attila Voras (NEVERMORE, LEANDER), James Murphy (TESTAMENT, DEATH, OBITUARY), Tim Roth (INTO ETERNITY), Jeff Loomis (Nevermore, SANCTUARY), Curran Murphy (SHATTER MESSIAH, Nevermore), John Perez (SOLITUDE AETURNUS), Rob Doherty (DIGITAL DOOMZDAY, Into Eternity), Mike Riggs (SCUM OF THE EARTH, ROB ZOMBIE), Mark Simpson (FLOTSAM AND JETSAM, BEAUTIFUL CREATURES), Jack Frost (SEVEN WITCHES, SAVATAGE), Carlos Alverez (SHADOWDANCE) and Pete Blakk (KING DIAMOND, DISASTERPEACE).

Listen to DiFabio detail this marathon of fretboard mastery below:

Single Bullet Theory's new album, IV, will be released on September 27th via Goomba Music.

IV is described as “a much more musically diverse yet [more] muscular” effort than the band’s previous releases, and it contains a nine-minute instrumental track called 'Auctioneer Of Souls'. The track features guitar solos from twenty of metals finest and is destined to become a classic."

Joining founding member Matt DiFabio (formerly of PISSING RAZORS) on IV are new members John Ruszin III (guitar), Jeff Kalber (bass) and international drumming sensation, Acacio Carvalho (drums).
