I think its a tie between Rush and BTO. BTO for the heavy vintage original all time great factor and RUSH for the chart topping grand touring and longevity factor.Acoustic? I had thought that i remembered the great Gordon Lightfoot was from Canada, and of course he is. Those of yous'e who arent geezers like me probably dont know who Gordon Lightfoot is. Well, I will tell you something. His songs are an acoustical tour-de-force of vintage acoustic music... as good or better than the best of any originals from the golden era. My alltime favourite is, of course, The wreck of the Edmund F.What a brilliant song! Man they dont write em like that no more!
