Lots of opportunities for self deprecating 3-word band names here!

True. Today's metal reminds me of 70s classic rock ... loud, fast, flashy, aggressive, exciting, grating ... mainly aimed at teenagers and early 20s.
What I have noticed is today's rock bands tend to be less eclectic - once you get a critical mass of things they start to specialise - be it job structures in workplaces, TV stations, hive animals, etc.
It's happened with bands too - I'm not seeing the eclecticism of The Beatles, The Stones, Hendrix, The Doors, The Who, Zappa, early Tubes, Led Zep, Bowie, Lou Reed, Pink Floyd, Joni Mitchell, King Crimson, Queen, Eno, ELP, Hawkwind, Roxy Music, Radiohead, Gong, etc.

Very true. I don't think I've seen as much interest in older forms by the younger generation before. Don't know what to make of that.
