Robert Wilson and Philip Glass's Einstein on the Beach returns for the first time in 20 years with the launch of a major international tour, starting with preview performances at the Power Center in Ann Arbor, Michigan, this weekend. These mark the first North American presentations ever held outside of New York City. "It's only January, but the classical music event of the year is already upon us," exclaims the Detroit Free Press. "Glass and Wilson strip down the fundamentals of movement, image, text and music to essentials and then elevate their essence to operatic grandeur ... It's hard to overestimate the impact of Einstein on American music, art and culture."

The Times of London gives it a perfect five stars, exclaiming: "Brilliant, audacious, original and, above all, entertaining; Punch Brothers put on a show that pushed the boundaries of excellence in contemporary music performance in virtually all directions."

To coincide with the tour and Glass’s 75th birthday, Nonesuch has reissued its seminal 1993 recording, which the Washington Post wrote is "more complete than the first recording and superior in both performance and sound."

Chris Thile and Michael Daves brought the music of their debut duo album, Sleep with One Eye Open, to the picturesque Allen Room overlooking New York's Central Park as part of Lincoln Center's American Songbook series. "They’ve been playing small club shows downtown, and they brought that informality to the Allen Room," says the New York Times, "punctuating dazzling virtuosity with bluegrass-aficionado banter and 'Fiddle Tune Request Time.'” Thile and Daves "sing and play the daylights" out of the tunes, says the Times, playing both with "breakneck" speed and "with restraint and delicacy."
