The last issue of Banjo Newsletter had an interview with Wade Mainer. There are claims (he didn't make them, but they were supported by some prominent musicians) that he was playing Bluegrass before the "Magic Night" that Monroe walked on stage at the Opry with a band that included Earl & Lester. I have never heard Mainer, they article says that he still plays remarkably well even though he is in his ninties. Any suggested listening?
