Punch Brothers ("Bluegrass" Band) - JS Bach Brandenburg Concerto 3-iii, Allegro in G Major

Bunch of bluegrass prodigies in one band--like the Cream of the genre.

Bluegrass might be unfair, but they play bluegrass instruments. And bluegrass-y music, but it's hard to compare it to, say, Ricky Skaggs. (Ricky Skaggs is still okay sometimes.)
