OK, just checked, Sierra Hull is now 30, Molly Tuttle 29, A.J. Lee is 24, Billy Strings is 29, mostly with players of their own generation in their bands... these players in particular have been playing since they were children, often from musical families (e.g. Molly Tuttle's dad, Billy Strings' stepfather were/are all players). Makes me think that the future of [this brand of] acoustic music is in safe hands...
