Aside from "rank[ing] among the most influential harp players in the Blues",[REF] Butterfield has also been seen as pointing blues-based music in new, innovative directions [REF].
In 2006, Butterfield was inducted into the Blues Foundation's Blues Hall of Fame, which noted that "the albums released by the Butterfield Blues Band brought Chicago Blues to a generation of Rock fans during the 1960s and paved the way for late 1960s electric groups like Cream" [REF].
