The Holy Modal Rounders, an American folk music group, was founded in 1963 by Peter Stampfel and Steve Weber. Known for their unique blend of traditional folk, country, and psychedelic rock, they played an integral part in the 1960s folk revival. Their offbeat lyrics and eccentric performances, notably on their influential album "The Moray Eels Eat The Holy Modal Rounders," set them apart. The band's use of unconventional instruments like the fiddle and banjo, combined with their idiosyncratic interpretation of American roots music, marked them as pioneers in the psychedelic folk genre.
