What do classical string instruments and metal typically have in common? Oh, about as much as peacocks and pink monsters - but that's the beauty of Judgement Day - the string metal sensation that originally emanated from the crusty streets of Berkeley set to hit Olympia's Northern this week. Tying all of this contradictory action together, Judgement Day released Peacocks/Pink Monsters, a "deluxe 20-page custom board book by Copter Design Studio, including an enhanced CD," according to the band's Web site, on April 13 - a mere week before the band's scheduled stop in Oly. The last time I witnessed Judgement Day in action the band was busking through ingeniously eccentric metal compositions with violins and cellos, causing the people-flooded streets of Austin during SXSW to come to a near standstill - in awe of the band's originality. Basically, you'd be foolish to miss these guys.
