Guitarist James Iha is still earning his Jimmy Page merit badge, and when he stretches out into one of his psychedelic guitar epics in a song he wrote and sings Believe, the soft-spoken interludes help set the stage for the moments when Billy Corgan swoops into his trademark squawk. Whether you love Billy or hate him, he has become a rock icon nerdy by nature, the boy with the least cake and a grown man who dresses like Little Orphan Annie. The new single gives Billy room to express himself, and it’s the catchiest argument for misery he has ever made.
