If you’re new to jazz and have Spotify, there is a Spotify-curated playlist called, “Jazz Classics.” If you’re doing it the old fashioned way, you could do worse than starting with these albums: Kind of Blue, Love Supreme, Mingus Ah Um, Red Garland’s Piano, Time Out and almost any good Charlie Parker compilation of which there seem to be dozens.
Between my Spotify weekly playlist and wdcb here in the Western burbs of Chicago I am a happy camper. I like miles Davis, Lonnie Smith, fusion jazz, and the like. Not a big fan of the big bands from days of yore.
Recently listening to some vocal jazz albums; I really liked Tony Bennett's When Lights Are Low.
Aside from that, Hot Rats is my album of choice right now: a timeless classic for all listeners, new or old.
