The Hampton String Quartet, considered by many to be one of the founders of the "alternative music" genré of chamber music, is a string quartet specializing in rock music and other popular styles, playing serious chamber music arrangements of songs using classical composer influences and frequently quoting or paraphrasing snippets from their works. For example, their arrangement of "Earth Angel" is a paraphrase of Johann Pachelbel's Canon in D, and Reed's "Ob-la-di, Ob-la-da" quotes Franz Schubert's "Erlkönig."
