580. The Nice

Perhaps better known now for being Keith Emerson’s band before Emerson, Lake & Palmer, the Nice had the distinction of being one of the early Progressive Rock Bands of note. Their blend of Psychedelic Rock with Jazz and Classical led to unique arrangements and though they were not a hit with critics or with a large assortment of fans, the groundwork they helped build was very important in launching the Progressive Rock genre as a mainstream musical option.
