For anyone partial to Roy Hargrove, this would be a fine week to be in New York. He is appearing Wednesday through Sunday at The Jazz Gallery with his quartet (pianist Danny Grisett, bassist Reuben Rogers and drummer Greg Hutchison). Each night, Hargrove will perform with a different fellow trumpeter. His guests will be, in this order, Darren Barrett, Claudio Roditi, Tom Harrell, Nicholas Payton and Marcus Belgrave. Hargrove can be uneven, but when he is inspired—especially playing ballads on flugelhorn—he creates melodies on a level with some of the greatest jazz soloists of any era. All five nights at the Jazz Gallery are virtually guaranteed to be interesting, but it is most intriguing to anticipate on the same stand Hargrove and Harrell, two of the most inventive trumpeters of our time. This pairing could fairly be called an event.
