Well, 80's music might bring back memories, but it's mostly the quality that counts. Considering that, I prefer the late 60's and 70's with Led Zeppelin, Jimi Hendrix, Bob Marley and so.
btw. these are the good ones between the popular. Who wants to remember ABBA (for the quality, not for the camp, that is)
Btw, anyone ever heard of DAAU (Die Anarchistische AbendUnterhaltung)?
It's a "new" (started in 1994 or so) Belgian rock/classic music band, it plays instrumental music, with cello, accordion and violin.
It's goooood. Especially "Lost Souls" and "Gin & Tonic"
