I can’t tell you the best album because I own none of them, a little before my time actually, but when I do listen to music, it’s always classic rock. Taking a bit of a break from tunes, because tunes and emotions don’t mix.

Some of my favorites though in no particular order:

Queen
Steve Miller Band
Boston
Styx
The Eagles… Oh my God, I love the Eagles
Lynyrd Skynyrd

Not even the tip of the iceberg, but these are who I listen to the most.
I play acoustic guitar sometimes and I find that classic rock was the era of GREAT guitaring. I don’t know what happened after the 80s.
