I'd never heard of Porcupine Hill before - cracking song.
Tree you mean? I would argue with that Spotify top 10 in areas, though the #1 spot is justified. If you like what you hear, then I envy you getting into that juicy back catalogue. I did it in 2015, what a trip.
Yep - sorry, Tree lol. I've been listening to them on spotify - really like them. Good blend of rock, pop, blues and prog !
