Ive heard a bunch of Ray Brown albums (or albums that happen to have Ray Brown). My all time favorite would have to be This One's For Blanton, but I think this selection would be a little more universally accessible to the most jazz fans. It is OOP now, so look for a used copy on Amazon or similar.
For those of you who already have This One's For Blanton, I'd recommend getting this:
The Duo Sessions
This is actually 2 Ray Brown albums (NOTE: NOT Ray Brown Trio) with Jimmy Rowles: "As Good As It Gets" and "Tasty !". Both albums are just piano and bass. One thing I love about a lot of Ray Brown music (this included) it that there is no recording hiss of any sort. Plenty of jazz albums that go way back have great sound quality, but often times there is some hiss as well. But RB material tends to be from the '70s and '80s and even '90s, so you get world-class recordings of world-class music, imo.
There is plenty of jazz that I love to death, but some are what I would consider 'focused listens', and some that I am always up for listening to. This falls into the latter category. I never tire of it .
