Here's a couple of essentials from my Record Collection:

This is my favorite Live album of all time. It's almost impossible to describe what it was like to see Wet Willie performing live in their heydey in the mid-to-late '70s, but this comes close.
It was always gonna be a great show when Wet Willie was the opening act, because it caused the headliners to elevate their performance or risk being embarrassed.

Steely Dan has always resonated with me for some reason.
