+4db is an a cappella quintet who's sound is as diverse as it is smooth. With a repertoire that ranges from jazz standards to contemporary pop, +4db straight-up swings and surprises. Formed in 1996, this award-winning ensemble makes its home in the San Francisco Bay Area. 1998 saw them champions of the Harmony Sweepstakes San Francisco Regionals, where they also earned Best Arrangement for the second year in a row. Their local success harbingered national accolades, with their memorable sound securing Second Place and Best Arrangement at the 1998 Harmony Sweepstakes National Finals. Judges aren't the only ones who dig the delicious harmony of these five voices. +4db has also won Audience Favorite each time they've participated in Harmony Sweepstakes regional and national competitions. +4db released their eponymous debut CD to much fanfare just this January.
