Yeah, they did, but I bet that Gene Ammons outsold them both, combined, at least at the time. The Miles/Trane Quintet albums were widely staggered in their releases, and I don't think that the last one came out until, when, 1962?
Prestige, remember, had "hits" early on. "Moody's Mood For Love" was a notable one, and I'm pretty sure that Jug was a big seller all through the 1950's, especially by the time that "Canadian Sunset" and "Angel Eyes" hit big. When I say "hit big", I don't mean "Top 40" big, but big in the blue collar African-American community. Those records were HUGE in that demographic. Given the relatively low overhead of the indie jazz label back then, anything that caught on outside of the hardcore jazz community would turn a nice profit, especially if it became a "jukebox hit". I think that companies made (make?) money on jukebox play, but I could be wrong. But I'll tell you this much - Gene Ammons was popular outside of the "jazz connesieur" contingent in a way that few post-Swing Era jazz artists have been.
