Yeah, the 'classic' rock of the 1960s and 1970s is still good. The Beatles, The Rolling Stones, and The Who are the triad tied for 'greatest rock band of all time' and then you've got other interesting but slightly less famous/influential bands like Jefferson Airplane/Starship, and Crosby, Stills, Nash & (sometimess) Young, or the Moody Blues. I think some of Zeppelin is good but they're not this 'fantastic' band that so many people seem to think they are. Some of the bands from the 1980s are pretty good but most of them turn out to have gotten started in the 1970s -- Genesis, The Talking Heads, Super Tramp, etc. (Hmm I guess Super Tramp was already famous inthe 1970s...
) U2 was around in the early 1980s, and I think their first few albums are actually their best. The 1990s and later are not looking so good. I wonder if the stuff being crapped out now will be considered 'good' in 30 or 40 years.
Besides the 'classic rock' field, though, I've become interested in various 'alternative' genres. But today the genres are so narrow that you'll usually only find a few bands that you like in any one category. Some of the so-called 'techno' bands are quite good. Delerium, for example. But lots of it is just boring noise. Same for 'New Age' music. Some of these artists are good, some of them are just useless and smarmy at the same time. Yes was much better 'New Age' music in its time. Too bad they've corroded so badly over the years. Can't stand any of their new stuff. (King Crimson, Pink Floyd, Yes, Alan Parsons Project and such stuff used to be called 'Art Rock' before all the sub-genres appeared.)
