Sun Ra - Space Is the Place
Al Di Meola/John McLaughlin/Paco de Lucia - Friday Night in San Francisco (latin jazz)
Miles Davis - Bitches Brew
Frank Zappa - Hot Rats
Albert Ayler - Love Cry

Once you're done with those go through the back catalogues of all the artists you've checked out so far, because they're all stellar.
