You know, I like the Beatles, but I never had a problem with Yoko. I remember everyone hating her, but I always thought she was scapegoated. I got one of her albums recently, and it wasn't bad. Probably too progressive for it's time. The scary thing is, I completely understand her art, or at least it speaks to me. Everyone thought she was so weird, and I think she's pretty cool.
I think I'm just a little older than you, Shawna, because I was listening to Gary Numan, Dead Kennedys (Jello Biafra just did a spoken word performance here in Dallas, kind of like a one-man poetry slam, but I didn't go), Modern English, Depeche Mode, Devo (Mark Mothersbaugh does a lot of incidental music for Nickelodeon, check the Rugrats credits), Johnny Rotten, The Clash, The Cure, The Jam, Elvis Costello & the Attractions, "The Artist formerly known as Prince" before the "1999" album, Mick Milk, XTC, Talking Heads, Tom Tom Club, Laurie Anderson, The Residents, tons of other people who don't come easily to mind, lots of import stuff that I don't remember much at all. I those people are about 5 years earlier than the folks you mentioned, though I listened to them too.
The alternative station in town was WLYN and their slogan was "Dancing at the Y, Y-102, WLYN in Lynn". Massachusetts, that is. Last I heard they were WFNX, having been bought by the Phoenix, Boston's alternative lifestyle newspaper. They aren't as cutting-edge any more, or maybe it's just time for another new musical aesthetic.
