My first thought was Buffalo Springfield.
After some thought, I think TP&TH are an even better choice.
The had a much longer run, many more memorable songs, and were “All-American”.
Not to denigrate the Buffalos, but the band was truly bi-national (izzat a term?).
Bassist Bruce Palmer and Neiler are/were Canadian.
Not that there’s anything wrong with that (so am I).
So RIP, and thank you Tom.
You left us all richer, and I miss you, man.
I think if your looking at sheer impact, record sales, longevity, songs that are the soundtrack of the US it has to be Aerosmith. And I’m not a fan per se but there music has been rockin since the seventies and there still going. So I guess I’m looking at it objectively.
