"The jazz-rock quintet Kneebody drew a lot of attention two years ago for its album with the electronic experimenter Daedelus. But the band has been around for more than 10 years, developing a cult following for its matrix-like tunes and punctilious execution. Kneebody is back to doing its own thing on “Anti-Hero,” a politically inspired and warm-blooded new album out last month on Motéma. The group celebrates the record’s release with a concert at Le Poisson Rouge on Saturday. This video, which has its premiere here, accompanies “The Balloonist,” written by band member Shane Endsley. Muscular drumming and distorted, suspended harmonies offset the almost nonchalant lucidity of Mr. Endsley’s trumpet and Ben Wendel’s tenor saxophone." G.R. Click here to see more
