Kronos Quartet performs at the Massachusetts Institute of Technology's Kresge Auditorium in Boston tonight as part of a music mini-marathon (in advance of this Monday's running of the full-length Boston Marathon) with Bang on a Can All-Stars, Wu Man, Gamelan Galak Tika, and the MIT Chamber Chorus, as part of the school's Festival of Art+Science+Technology. Curated by Evan Ziporyn, MIT's Kenan Sahin Distinguished Professor of Music, tonight's five-hour concert features the world premiere of Tod Machover's Chomsky's Suite, with special guest Noam Chomsky, video by Joan Logue, and visual effects by Peter Torpey; selections from Terry Riley's The Cusp of Magic; and performances of Christine Southworth's Super Collider, and Brian Eno's Music for Airports, among other works.

On Sunday, Kronos performs works by Riley, John Zorn, Bryce Dessner, Sigur Rós, Café Tacuba, Clint Mansell, Ram Narayan, and Aleksandra Vrebalov at The Palladium in Carmel, Indiana.

Last weekend, Kronos performed Steve Reich's WTC 9/11 in a concert titled America Program, featuring all American composers at the Clarice Smith Performing Arts Center in Maryland. The concert, says the Washington Post's Anne Midgette, "did a lot more than just present American music. It offered some thoughtful perspectives on what it means to be American—without lecturing, without analysis, simply through music. It may have been the best match of idea and execution I’ve heard from Kronos, ever." Read the review at washingtonpost.com.

Randy Newman performs two shows in the Pacific Northwest this weekend, at the Aladdin Theater in Portland tonight and the Atwood Concert Hall in Anchorage on Sunday. Newman spoke with Willamette Week in advance of tonight's show; you can read the interview at wweek.com.

The Ottawa Citizen called Newman's recent performance there as "superb." All About Jazz, reviewing the show, wrote: "Newman writes about the human condition ... and about the multitude of matters concerning life, love, politics, and pretty much anything else that the multifarious charms and peccadilloes of said condition impact, and he does so with a rare combination of astute personal awareness and a broad world view that makes his sometimes satiric, sometimes poignant, and occasionally downright painful songs resonate in ways that transcend time."
