Swinging grooves filled the air in the 1940s and '50s jazz clubs in Manhattan, Miami Beach and Los Angeles. Dizzy Gillespie and Ella Fitzgerald mesmerized audiences, and you can, too, in your own jazz-themed rec room. Think retro-lounge vibe with plenty of velvet and mood lighting. If you want to throw in a little Miami, add some pink flamingos and palm fronds. If your jazz look is more Cotton Club, ditch the beach accessories and go with some classic jazz prints and performance posters. Make sure you have plenty of be-bop on hand and some room to cut a rug if the spirit moves you.
