MURFREESBORO, Tenn. (AP) - The Grammy Foundation has awarded a nearly $20,000 grant to a university music center to digitize a historical collection of live bluegrass audio recordings.

Middle Tennessee State University's Center for Popular Music will digitize a collection from Indiana music lover Marvin Hedrick.

The university said in a news release that Hedrick, of Nashville, Indiana, recorded Bean Blossom Bluegrass Festival performances and backstage jam sessions as well as impromptu sessions at his radio and TV repair shop. Hedrick died in 1973.

Hedrick's sons, Gary and David, donated 167 open-reel tapes, other sound recordings and photographs to the center last year for preservation and archiving.

The Center for Popular Music is part of MTSU's College of Media and Entertainment and recently marked its 30th anniversary.
