We went to a Paul Simon concert with friends recently (yes - we're that old). It was a terrific show.
But the opening act caught our attention also. The band was technically "progressive bluegrass" - think soundtrack to Oh Brother, Where Art Thou? Think guitar, fiddle, mandolin, bass, and banjo.
They were great. Intricate, complex, and fast. Really fast.
At one point my husband turned to me and remarked about how incredibly quickly they all moved their fingers; they were flying.
"Think what I could do if I could move my fingers that fast....."
