60s Hendrix (Bufflo Springfield, Joni mitchell -I know she is not a group but she ruled the singer song/song writters of that time-)

70s Allman Brothers (Eagles)

80s Arrowsmith (Journey, Heart)

90s Counting crows (I really got into women singer/ song writters like Shawn Colvin, Tori Amos, Sarah Mclaclan in the 90s)

From 2000 on I have not heard a lot of music that I can actually stand. Deregulation legeslation, the resulting republican Clear Channel radio dictatorship, Auto Tune, and Click Tracking pretty much distroyed music durring that time period. Thank God for Jeff Beck and Joe Bonamossa.
