Writing the perfect pop tune that puts across a message in under four minutes while keeping to the three-chord, verse-chorus-verse formula isn't as easy as it seems, and pulling it off without sounding like corporate schlock or AOR dreck is an even greater feat. The Complements never cross that line - their EP bristles with tight harmonies and solid accompaniment, courtesy of musicians like Mark Kelso, John Dymond and Steve Klodt, who've played with everyone from Pete Townsend to Shania Twain. Kevin Zarnett and Nurit Suzana are the band's nucleus, trading off on lead vocals in songs about coping with the end of a relationship. Don't worry - their strong writing avoids the sappy clichés that bogs down lesser breakup discs. The Complements launch their CD at the Rivoli Wednesday (February 2).
