Danny Bank was probably the third bari player I knew by name (Carney & Mulligan being the first two), thanks to his appearance on a Music Minus One album that my high school had called FOR SAXES ONLY. It was an album of sax section w/rhythm section pieces composed and arranged by Bob Wilber, "minus" a tenor player on one side and an alto on the other, with you, the saxophonist in the comfort of your own whereever, playing the missing part. The section included Hilton Jefferson and Wilber on altos, Jerome Richardson & Seldon Powell on tenors, and the hero of our story, Danny Bank on bari, he being the only sax player to be heard on every tune on both sides of the album.
Bank shows up on all kinds of larger ensemble dates, easily as many as Pepper Adams, and probably a lot more because of his doubling ability. It's easy to get the impression that the NYC studio scene of the 50s & 60s wasn't very competitive, so often do we see the same section players on album after album after album. That would be incorrect - the competition was fierce. guys like Danny Bank got the call so many times becasue they were master musicians, and good deliver the total package of section playing (which is becoming something of a lost art afaic) quickly, consistently and reliably every time out.
In short, Danny Bank is a master musician!
