I didn't know anything about Jazz, untill I was given about 50 lps. Played, hey, I like trombone, hey, I like Red Garland, hey I don't like big bands. Armed with that start, off I went into the world of Jazz.
You will discover what you truly like,
and you will listen to LP's you will more than likely never listen to again. Sell/trade/give away those, keep room on your shelves for more like the ones you really respond to.
After you discern what you like, then research and buy similar, as well as what types/composers/conductor/orchestra are not included in what you bought.
