A bunch of jazz musos from Los Angeles with a harmonica player from Denmark. They became one of the more fun US pop bands of the 70s, first gaining exposure via a shared-billing album with Eric Burdon (featuring "Spill the Wine"), then moving on to have a string of hits on their own, showing much more range than their funk band peers - "Slippin' Into Darkness", the latin-rock "Low Rider", which has lived on in TV commercials, the sing-a-long "Why Can't We Be Friends?", et al. Classic stuff.
