Jazz artists who aren't always as cheesy as their reputation would have it

Grant Green- Solid. That's one heavy album. Standard.
Lee Dorsey- Search For The New Land. Utterly spellbinding modal explorations, not just peppy soul-jazz in a Sidewinder vein (nice tune though that is).

Any more cheesemeisters (or near cheesemeisters) who have at some point sat down and down and made some really serious albums?

Goodness me, what a crazy thing to type. Brain not connected.
