I’ve had a chance to A/B the Go West! box pressing of Way Out West versus the OJC, and you described the differences almost perfectly to my ears. Rollins’s tone is definitely fuller and more lush on the BG cut. The bass clarity and presence is probably the most obvious distinction. It’s like a different album from a bass-focused perspective. Drums and cymbals are more laid back for sure in the BG cut compared to the OJC, which has more of a live and forward vibe on the drums and cymbals (especially the cymbals, which are really in your face on the OJC). Rollins’s tone is more lean on the OJC but it cuts straight through in a way that some people might prefer.
For me (and my ears and system), these kinds of differences are consistent with differences in how I perceive RKS and BG cut jazz reissues compared to KG. The former seem to have more warmth and midrange and low-end guts compared to KG who seems to emphasize the outer edges a bit more, particularly in the high range. I’m not saying KG’s cuts sound like dried jerky. I have plenty of his reissues that I really like — a lot — but I consistently prefer cuts by these other guys in the jazz realm, at least.
In any event, regardless of what I think and how shitty my ears might be, I highly recommend the Go West! box, especially if you can get it for under $40 like some of us were able to. I wasn’t even looking at this box b4 that Movie Mars sale bc I was happy with the OJC Way Out West, but I’m really glad I pulled the trigger.
