It is unusual to have all five of the Los Lobos band signatures on one item but here it is! Los Lobos ("The Wolves") are a multiple Grammy Award–winning American Chicano rock band from East Los Angeles, California. In 1987 they recorded some Ritchie Valens covers for the soundtrack to the film La Bamba, including the title track which became a number one single for the band. In 2009 they even performed at the White House. Signatures include: David Hidalgo, Louie Perez, Cesar Rosas, Conrad Lozano and Steve Berlin.
