I'm biased when it comes to Rypdal myself, as I love (& own all of) his work. Seeing him perform live in NYC last year was a great experience as well and even with obvious health problems hobbling him, he's still an amazingly adroit player.
The "Odyssey" box was a revelation to me, as it included the album in its entirety, as well as an unreleased live set from the era, which cooks. Yes, a bit on the heavier side, but still full of the trademark Rypdal sense of atmosphere, fluidity, and poise, and with a helluva band behind him. Essential, as far as I'm concerned.
