One of the major bonuses associated with the Thelonious Monk Institute of Jazz moving to New Orleans is the low-key presence of some of the most interesting players in the world of jazz.  They come to the institute’s home at Loyola University to teach master classes and otherwise impact the students in the program.  They also occasionally play gigs that are open to the public.  Since he burst on the New York scene as a college student at the Manhattan School of Music, the pianist Jason Moran has been turning heads with his singular approach.  Tonight, March 4, 2010, he appears with one of New Orleans’ masters, the drummer Herlin Riley at Snug Harbor.
