Multi-part documentary, being shown on PBS. Tonight was part 2, up to 1945.
So far, it is awesome. I'm learning a lot. I'm only a casual country music fan. But this is great stuff. Awesome pics and footage, too.
also saw it last night as well as tonight. thoroughly enjoyed it. Ken Burns always does a bang up job. like the OP stated, learned a lot and looking forward to tomorrow as well. do yourself a favor and tune in.
