I'll respectively disagree that Undercurrent is not a sideman gig for Bill. On the inside of the gf it lists his name first and in larger letters and Bill made at least one more album on UA so this might be under his contract. I like the album but the sound on the original lp is not very good. I bought my copy from an old friend and he wrote the date he purchased it on the inside of the gf which was August 1962. It is disappointing for a first press. There's an interesting story on the London Jazz Collector website about his quest for a good sounding pressing and discovered that Toshiba-EMI is the one to get. Story is here. Bill Evans Jim Hall: Undercurrent (1962) Toshiba-EMI I've never heard that pressing but would snap it up if the price wasn't scary.
