Ten Years After is a British blues-rock band that rose to prominence in the late 1960s and early 1970s. Notable for their high-energy performances, the band's distinctive sound was largely shaped by guitarist and vocalist Alvin Lee. Their performance at the 1969 Woodstock Festival, particularly Lee's extended solo on "I'm Going Home," significantly increased their profile. Their song "I'd Love To Change The World" from the 1971 album "A Space in Time" remains one of their most influential and recognized works.
