I've just discovered Dennis Gruenling's radio show with show dating back to 2006 I think, so much material streamed for great value. Way better than spotify. Check out http://bluesandthebeat.com
outta the blue i suddenly can do a 2 hole draw. key of A harp. i then had an epiphany :) now i can FINALLY do some improv, (40 plus years keyboards, bands etc.), and just sit and wail away. 10 weeks later and the magical 2 hole :) Love it. THANKS DAVE. It really helps when you set realistic goals fro students within a given time frame reference. I would have gotten a bit frustrated if you had not said "about" how long such and such would/shoulod take. One year until retirement and I can't wait to sit and suck and blow. :0
