That is a genuinely good question. The 1960's had The Beatles, the Rolling Stones and The Who, the 1970's had Queen, Merle Haggard, and Lynyrd Skynyrd, the 1980's had Van Halen, Talking Heads, and Mötley Crüe, and the 1990's had Primus, Nirvana, and Alice In Chains.
I just don't know, man. I just don't know.
