This one hit me hard. Boston was one of the first albums I ever bought.
If you've never read about it, there's some cool history of the drum tracks on the first demos that Tom Scholtz submitted. Tom, being a perfectionist, knew the tracks were good. Some pencil neck at the record label told him to redo the drums. He went home, sat on the recordings for a bit, then resubmitted the same damn tracks and the pencil neck loved them.
Never saw them live, other than listening to a late-afternoon sound check when they appeared at Rutgers in the late '70's. I was outside the College Ave. gym and even from there it was extraordinarily loud.
