Kronos Quartet performs two distinctly different sets at the Monterey Jazz Festival Saturday night. First up, on the Arena / Jimmy Lyons Stage, Kronos pairs with the Billy Childs Quartet on Music for Two Quartets, a piece Childs wrote for Kronos. Later that night, the festival's Night Club hosts a solo set from Kronos, featuring works by Bryce Dessner, Sigur Rós, Thelonius Monk, and Ramallah Underground. The group has posted a video of its music director and violinist David Harrington to Facebook, in which he discusses both programs.

San Jose Mercury News music writer Richard Scheinin includes the Kronos sets among the festival's "not-to-be-missed acts." Says Scheinin: "The No. 1 string quartet of contemporary classical music, and somehow still in the vanguard after 30-plus years, Kronos is a great band."

The Black Keys continue their tour with Kings of Leon and The Whigs with two performances in Florida this weekend: tonight at the Cruzan Amphitheatre in West Palm Beach and Saturday at the Ford Amphitheatre in Tampa.

This duo "can rock harder than most bands can do with twice as many members or more," says the Palm Beach Post. "That’s the way it’s always been for The Black Keys ... Fans and critics alike have praised them for albums like 2003’s Freakthickness, 2004’s Rubber Factory, 2006’s Magic Potion, 2008’s Attack & Release and now Brothers."

Finally, this Sunday is "Gamelan Sunday" at the Bozar Center for Fine Arts in Brussels, bringing a full day of concerts, workshops, and dance devoted to Indonesia's rich musical heritage to the hall. Included throughout the day are a number of events showcasing the traditional musics of the islands of Bali and West Java, which were featured on the groundbreaking Nonesuch Explorer Series recordings of the 1960s. The day's capstone event is an evening concert that brings together the gamelan and works by Steve Reich, who was influenced by that music.

The Sundanese group Kyai Kyai Fatahillah performs an arrangement of Reich's Six Marimbas, and the Balinese group Gamelan Semara Raith performs 18, an homage to Reich's Music for 18 Musicians, written by Evan Ziporyn (who can be heard on the just-released Nonesuch recording of Reich's 2x5). The latter piece was premiered earlier this month by Gamelan Semara Ratih at Tropentheater in Amsterdam. You can watch a rehearsal here.
