Chilling in Baltimore waiting on my flight to Indy. Listening to The Punch Brothers... If you don't know their music, you have not lived. Put atonal chamber music, with bluegrass and virtuosic musicians, blend it together and you get Punch Brothers! (Think whole tone scales played by a banjo... Yah it's that awesome!).
Can you count the key changes???
