ABC has a couple of oddball jazz labels, as I recall. I have a Scott Bradford album released on their Probe label. Not sure what the different labels were meant to accomplish. Marketing, I guess...
Edit: also, it looks like MCA picked up the Impulse label in the 1990s. I have a remastered 180 gr. Duke Ellington & John Coltrane disc dated 1997. One of the classics with them, Elvin Jones, Aaron Bell, Jimmy Garrison, and Sam Woodyard.
