Best Unknown Jazz Album


Yeah, everyone raves about Mile Davis' "Kinda Blue" and Coltrane's "Blue Train". But what is the best unknown jazz album in your collection?

Bug Music, by Don Byron. It's a recent release, so it qualifies more as not yet well known.
This is on Blue Note.I've probably played this disc(lp+cd)more than any other in the last 6 months.
I'll probably make a more extensive here later this evening, after I get home from work, but the first album that jumped to mind that fits the "best unknown jazz recording" is a duet by Bill Evans and Jim Hall titled "Undercurrent". One of my all-time faves that got a 5-star rating from Downbeat in the early 1960's. More suggestions later.......
Agreed about Undercurrents. They also recorded another album together but I can't remember the name and haven't heard it.
