Už Jsme Doma (that's easy for you to say) is the greatest Czech band that I know. Granted, they're just about the only Czech band that I know, since I have never Czeched out (sorry, I'll stop now) The Plastic People of the Universe, tho I know I should. (Robert Christgau says that The Plastic Peeps are his favorite prog band, so that probably put me off them a bit.)
These crazies hit the American college radio scene with this 1990 release and subsequent tours, and appear to still be going strong. "Uprostøed Slov" is an ADD-riddled affair that unpredictably veers from complex prog, to Residential high-voiced silliness, to hardcore punk - and that's just in the first song. What sounds like chimes, penny whistle, violin, and marimba compete with aggressive rock instrumentation, and vocals that range from operatic to punk shoutiness. There's a humorous air to the performances that leads me to think that their lyrics are probably pretty funny, too. (Can anyone confirm?) Listen to, say, "Soubor opatøení" if you think you don't like "progressive" rock. It is some whacked-out, fun stuff - prog you can pogo to.
Už Jsme Doma: "Uprostøed Slov"
Central/Eastern European pop/rock seems to be either the cheesiest of Eurovision/schlager pop and techno disco, or, on the other hand, complex classically-inspired metal/prog rock and jazz. Is there nothing in the middle? Poland's Gameboyzz Orchestra spring to mind with their nutty video-game pop, but otherwise I'm stumped. Maybe the trashy fun of (some) American music is a reflection of our trashy culture. Or maybe we're just too dumb to know how to dance in 14/8 time...
