Honestly I would suggest starting with classics and moving forwards based on names you see again and recognize - Jorge Ben, Gal Costa, Gilberto Gil, Caetano Veloso - start with those and then just keep moving forwards. There are a number of great books as well, but the best ones are all in Portuguese.
Flights to Rio are looking super affordable right now, just saw one for $450 round trip...tempting!
