Rock duo Tenacious D, comprised of actor/comedian Jack Black and Kyle Gass, has replaced Beastie Boys at the second Outside Lands Music & Arts festival to be held August 28-30 at Golden State Park in San Francisco, CA. The musicians were called in to fill a whole in the lineup caused by the last-minute withdraw of headline act Beastie Boys.

The duo will be headlining the final night with Ween, Modest Mouse, MIA, Band of Horses and others appearing on August 30. The event marks their first performance in the Bay Area in three years and their first festival concert in the United States.

In a July 20 video posted on the group's Web site, Adam "MCA" Yauch of Beastie Boys stated that the rock-rap crew is cancelling its upcoming tour dates and postponing the release of its new album while he undergoes treatment for cancer, including urgent surgery.

Yauch was diagnosed last week with a tumor in his left salivary gland. Because it was diagnosed early enough, it is treatable, and his vocal chords will not be affected.

Miley Cyrus dominates the daily tour recap for June 3, along with other updates including Paul McCartney, as compiled by TicketNews.

Tween phenomenon Miley Cyrus has sent her young fans into a frenzy with the announcement of her latest tour, which kicks off in September and features only paperless ticketing. A teen idol from another era, Paul McCartney will be performing in New York this July, and tickets to see that living legend go on sale June 15.

Coldplay and Beastie Boys will headline the fourth edition of the Osheaga Music and Arts Festival in Montreal, QC, from August 1-2. Coldplay will play on August 1, followed by Beastie Boys on August 2.

Bruce Springsteen and The E Street Band, Phish, the Beastie Boys, Nine Inch Nails, Wilco, Al Green, David Byrne, Snoop Dogg, Elvis Costello and Erykah Badu are among the initial round of artists confirmed for the eighth annual installment of the Bonnaroo Music and Arts Festival, June 11-14 in Manchester, TN. The event was founded and produced by Superfly Productions and A.C. Entertainment.

This year’s event marks the only 2009 festival appearances by Springsteen and Phish. Phish will play two shows – a full two-set performance as well as an additional late-evening set. Their appearance also holds special significance since the group has performed at the festival in various incarnations over the years, and their own festivals were one of the major inspirations for the creation of Bonnaroo and its operational strategies. Many of the organizers of Phish’s multi-day camping festivals were brought on to help with the creation of Bonnaroo in 2002 and continue to play a major role in the festival today.
