I love these guys! Hollywood Undead was arguably the first band to successfully use MySpace as a ways to jumpstart their music career. Within a mere months, the six-piece hip-hop/rock band from Los Angeles developed a cult following of thousands that enabled them to find success beyond cyberspace. Last year the hockey mask-donning musicians dropped a debut album, Swan Songs, about their hometown’s unglamorous side, youth subcultures, and of course, failed relationships. The vitriol music alternates between being perceptive and just plain vulgar–much like that of the band’s influences Eminem, The Used, and Nine Inch Nails. Listeners curious as to what lies behind Hollywood Undead’s masked fury are in luck: the boys have recently begun revealing their faces to the crowd at the end of each show. I hope they’re hot.Showbox SoDo, 1700 1st Ave. S., 652-0444. www.showboxonline.com. $20-$22.
