Sound Theories Vol. 1/2 is a double-live CD capturing legendary guitarist Steve Vai's electrifying collaboration with the Netherlands Metropole Orchestra. The two-disc set spotlights rare material culled from five European performances, a studio session and a soundcheck rehearsal recording, all of which took place between mid-2004 and 2005. Volume I features Vai playing guitar with the Orchestra, which has earned worldwide acclaim backing artists ranging from Mike Keneally, Terry Bozzio, Tony Bennett and Natalie Cole to Nancy Wilson and the Yellowjackets. Together they bring new life to both existing and never-before-heard Steve Vai songs, including "For The Love Of God", "Liberty", "The Murder" and "The Attitude Song", among others. Volume II features the Orchestra performing compositions penned by Vai, including "Shadows And Sparks" and "Bledsoe Bluvd". Says Vai, "The pospect of getting your music performed by an orchestra when you're only considered to be an over-the-top electric rock guitar shredder seemed virtually impossible. To be able to hear your music performed is the greatest gift a composer could hope for." Instrumental Guitar (Electric (Heavy)/Hard Rock), total running time, 1.5hr - Steve Vai @ iTunes!
