Sum 41 Half Hour of Power (Island Records) Sum 41 shows off a decent sense of humor on its new album, Half Hour of Power. Unfortunately, its supposed to be a band, not a stand-up comedy troupe. The album starts off with a satiric poke at Satanic-themed heavy metal with Grab the Devil by the Horns and **** Him up the ***. The band redoes a pack of familiar-sounding 1980s thrash metal riffs over a wordless minute, which, combined with the title, clearly skewers the excesses of the genre that spawned Metallica, Anthrax and Slayer. The rest of Sum 41s album is not quite as clever.
