Ottmar Liebert with Luna Negra

They were excellent, Ottmar a classical guitarist.  He had  a bass guitar and a percussionist accompanying him.  The way they listened and complimented one another was just excellent.  It was at the Musical Instrument Museum which I've been to, but never to a concert there.  I really like the museum itself and need to go back.  I have not been back again since it opened several years ago.
