I think we all have opinions on the greatest non-American rock & roll band. The Stones, Zeppelin, Beatles, U2, Pink Floyd, Black Sabbath, Deep Purple and others in the mix. But when it comes to American bands, it becomes more blurred (I think). For sheer longevity and relevance, it's hard to beat Jimi Hendrix Experience or The Doors, both going on 45 years with prominent influence and airplay. But both bands not working in their true form since 1970. Aerosmith is still around, but has stunk since the 70's. Tom Petty is still gigging, but most of his hits are way older. Kiss is still around, but they were only good with Ace Frehley for about 5 or 6 years. Plus they alienate a bunch of people. Pearl Jam has been at it going on almost 25 years, but again their earlier stuff is what gets the most airplay. Allman Brothers have been at it since forever. ZZ Top? I'm making a case for Jane's Addiction. First 3 albums were very innovative, yet still hard driving rock. Called it quits, then realized their greatness and reformed. My other case is for Living Colour. Killer musicians with a nice catalog of material and still playing live. And the Twilight Singers because they are the best band ever. I've had a bottle of wine and 2 beers. .
