The Kottonmouth Kings have followed this model brilliantly for the past decade, wrapping punk, rap, and reggae into a marijuana-scented package. The group collaborated with Insane Clown Posse on its full-length debut, Royal Highness, after which its "Down with the Krown" fan base dilated like a pothead's pupils. Live, the Kings stage circus-style spectacles (including a dancing mummy) that attract curious concertgoers who would normally avoid the band's music like a syringe on the beach. It's been an impressive run, but the Kings' career might be going up in smoke. This year's No. 7 suggests that the band has emptied its cornucopia of punning, cannabis-related album titles. The Kings now lace their joints with crunk juice, but these grimy get-low sounds have alienated longtime listeners. Like fellow burnouts Cypress Hill, the Kings are becoming a casualty of their target audience's famously abbreviated attention span.
