Muse would have been connected to Prestige in the sense that a lot of the artists that Don Schlitten produced at Prestige followed him to Cobblestone, and then when Fields and Schlitten split, some of those same cats went to Muse. Or so it seemed. Jimmy Heath, Sonny Stitt, who else, if anybody? James Moody never went to Cobblestone, but showed up on Muse after his run at Prestige (via Milestone?).
Too much math for R&B, but it was a good label w/a diverse catalog. They got a little predictable in some ways, but they were showing signs of tapping into a new scene centered around young guys like Graham Haynes, Gary Thomas, Kenny Garrett, Lonnie Plaxico, Cindy Blackmon, Geri Allen, Wallace & Antoine Roney, etc. A lot of M-Base cats doing "straight ahead" dates that might have grown into something substantial, but maybe not. We'll never know, because the label folded before the players had a chance to grow and solidify whatever it was that they were working on with their work for the label. Try and imagine what would have happened to all the Blue Note heavyweights of the mid-60s if that label had folded around 1959 or 1962 - where would they have gone, and would they have been able to grow like the did? Who knows?
Tell you what, though - it was a label that put out a LOT of stuff. Reissuing it all would not be simple!
