Now the group has launched a new website, jamesfarmmusic.com, with songs from the new album, photos, a free download, and more on the project. All About Jazz says the album "positions this über-quartet of established and rising stars as a clear force with which to be reckoned." Jazzwise gives it four stars, saying it "draws out a rich melodic seam of group inventiveness." The Revivalist says the band sets "a new bar for themselves and the genre of Jazz as it continues to evolve.” The world tour begins next week.

Steve Reich's 75th was celebrated in style at Carnegie Hall Saturday night with an all-Reich concert that included the NY premieres of WTC 9/11, Mallet Quartet, and 2x5 and a performance of Double Sextet. Carnegie Hall "assembled a starry roster of new-music ensembles," says the New York Times, "and the results will be hard to top." NPR says the concert showed that Reich "continues to make innovative music and is still one of the most important and influential voices of our era." The pieces "were individually marvelous," says SPIN, "and collectively provided a terrific summing up of what Reich is all about ... [E]very piece of the evening was a small miracle." The composer and performers head next to London for Reverberations, the Barbican's two-day celebration of Reich's work and influences.

Yeats—was featured on NPR's Weekend Edition Saturday.
