The lineup for the 30th annual Bridge School benefit concerts was announced earlier today. The events, featuring mostly acoustic performances by a variety of artists, are a tradition held every October at the Shoreline Amphitheatre in Mountain View, California, and organized by Pegi and Neil Young.

Connections, controversy

This year's concerts, taking place on October 22 and 23, feature many artists who have been associated with Neil Young in some way throughout the years. Nils Lofgren, Dave Matthews, Norah Jones, Willie Nelson, and the "Cowboy Hippie Surf Rock" of Promise of the Real -- Young's current collaborators, featuring Nelson's sons Lucas and Micah -- have all either recorded or toured with Young.

Also scheduled to appear are Metallica, case/lang/veirs (Neko Case, k.d.lang, Laura Veirs), My Morning Jacket, Cage The Elephant, and, curiously, Pink Floyd founding member Roger Waters. In 2014, Waters wrote a letter to Young's manager, urging the singer-songwriter to cancel his scheduled July Israeli concert with Crazy Horse. The eventual decision to cancel the show was reportedly made by Tel Aviv police, citing "tensions which have rendered the event unsafe," and not by Waters' request for a boycott. Waters, along with Young, the Rolling Stones, Bob Dylan, Paul McCartney, and the Who, is appearing at the “Desert Trip” festival, also in California, earlier in October.

In addition to Young, Willie Nelson, Metallica, My Morning Jacket, Lofgren, Matthews, Jones, Case, and lang (sic) have previously appeared at Bridge School Benefit concerts.

Bridge School Mission

The Bridge School was founded after two of Young’s sons were born with disabilities. The mission of the non-profit organization, according to its official website, “is to ensure that individuals with severe speech and physical impairments achieve full participation in their communities through the use of augmentative & alternative means of communication (AAC) and assistive technology (AT) applications and through the development, implementation and dissemination of innovative life-long educational strategies.”
