I am so sick of people saying the best rock and roll band EVER is/was Pink Floyd or Led Zeppelin.
Yes both bands were very good and there still hasn't been really comparable to either. But with that said, there are more original bands that are still coming out that are either on or close to that level.
I just have a problem hearing it because it is becoming a fad to like older bands that weren't around during your time (the vintage/retro era is coming). With a large selection of creative and original bands coming out in a society that is becoming relatively unoriginal and is starting to reuse old idea, it would be better for you to broaden your musical knowledge and help progress imagination and creativity.
Do you like Pink Floyd? Do you like Led Zeppelin? Then pick up an instrument and try to play what you think is up to their level of music while not necessarily playing the same type of music. Go, I challenge you.
