SACD...mono...Prestige Records...I have most of this on mp3 as well.
SQ = 5 of 5, the mono playback is very clean, great sound stage...The drums, and surprisingly the sax comes thru stronger than the mp3.
Content..this is either a '56 or '57 recording, so it's among the earlier works with Coltrane as a band leader...ranks behind Blue Note and A Love Supreme in my collection but if you're Coltrane fan, you'll like this one..
