I've always liked Noel Gallagher. Along with lead singing sibling Liam, he was the driving force behind the seminal Britpop band Oasis. An all-too-common scenario, the Beatlesque band was hugely successful in their native England, less so in the US.
I'm still thinking about REM. I can't help it. Not only were they one of America's most influential bands, they were important to me. They did more to keep the spirit of the '70s alive than any other band I can think of, while simultaneously helping to spearhead indie rock, that most '80s of movements in pop music.
