Yeah a case could be made for ZedZed. A lot of other bands were great but for whatever reason didn’t last all that long. Allman Brothers, Skynyrd etc. Tom Petty and the Heartbreakers (my fav) would be in the mix if FM radio didn’t shun him 20 years ago.
I always say, at most a band can expect to be relevant for about 7 years, before they turn into a nostalgia act.
