US rockers REM are joining forces with Ryan Adams and Idlewild to create a tribute album to 1970s band Big Star. Disc BIG STAR SMALL WORLD will feature a series of cover tracks including YOU GET WHAT YOU DESERVE and BACK OF A CAR. Big Star will also contribute a song - HOT THING. The disc will be released this month (MAY06), but the idea was originally conceived in 1998.
