Tony Allen's North American tour returns to New York City for a two-day stretch featuring two free outdoor performances plus the late-night Jump 'n' Funk at (Le) Poisson Rouge. Allen's recent show in Chicago was a critic's choice for Chicago Reader, which says: "Allen merges James Brown funk with jazz, highlife, and traditional West African rhythms, and his calling card is a doubled-up kick-drum accent that's weighted like a heartbeat, pinning his grooves solidly to the earth no matter how intricate his syncopations and permutations get up top."

The Punch Brothers new album, Antifogmatic, is out tomorrow and is streaming in full all week at Spinner. Their Bonnaroo set is now online via NPR.

The Star-Tribune, reviewing their opening set for Steve Martin in Minneapolis, raves: "Punch Brothers were creative, exciting and wow-inducing." The Independent calls the new album "coolly fascinating."

Tune in to watch legendary drummer Tony Allen on Late Night with Jimmy Fallon tonight, sitting in with the show's house band, The Roots. He kicks off a week-long North American tour this weekend. The A.V. Club says Allen's new album, Secret Agent, "expertly blends jazz, funk, and rock into earthbound extraterrestrial jams." It is "an undisputed fact of science that Allen," insists Time Out, "ranks among the globe’s funkiest residents."
