I remember owning the original LP back when I was 16. Thought the band was great. Tried to listen to it decades later and realised how badly it had aged. IMHO. Now I understand why my parents winced whenever I played it.
Reaction to possibly the best live rock performance I've heard. Grand Funk
Always loved Grand Funk, especially in concert. I saw them 3 times as a youth.
I found this great reaction video from a younger guy hearing them for the first time, singing one of their best songs, Inside Looking Out.
If you're young this'll show you why us old farts are so hard on most current music.
It doesn't get much better than this.
