Dave Matthews Band's LeRoi Moore was injured yesterday in an ATV accident which took place on his Virginia farm. The band has reported that Moore "was immediately transported to the University of Virginia Health System for treatment where he remains in serious condition." Stepping in for Moore while he recovers will be Béla Fleck and the Flecktones' Jeff Coffin. Coffin will be on hand when the group performs this evening at Charlotte, NC's Verizon Wireless Amphitheatre.

Woodstock icon Richie Havens will release his next studio album, Nobody Left to Crown, on July 29. The folk-rock visionary has been a mainstay on the live-music circuit since the 1960s and still clocks in more time on the road than musicians half his age. Since opening Woodstock, Havens has played everything from the Jammy Awards to Bill Clinton’s 1993 Presidential Inauguration and tackles a number of current social issues on Nobody Left to Crown. Havens’ Never Ending Tour continues this week with a stop at England’s Guilfest Surrey on July 5.

As previously reported, the City and County of Denver, CO declared last Friday Widespread Panic Day in honor of the group’s 32 sold-out shows at Morrison’s famed Red Rocks Amphitheatre. Meanwhile, within the city limits, Cervantes Masterpiece Ballroom was preparing for the Rocky Mountain Power Jam, which featured Jerry Joseph, Ivan Neville, Col. Bruce Hampton, former Black Crowes guitarist Marc Ford, Dexter Grove’s Steve Drizos and Bobby Lee Rogers & the Codetalkers. Before their gig, both Neville and Ford stopped by Red Rocks to play on a run from “Vampire Blues” into “10 Makes Sense To Me” and “Slippin' Into Darkness,” respectively.

A night later, longtime Panic associate Eric McFadden stopped by the venue after performing with his band in Utah to sit in with Widespread on a cover of Talking Heads’ “Life During Wartime." Finally, last night hometown hero DJ Harry jammed with the group on an improvisational segment that segued out of his mid-show DJ set. Widespread Panic will appear at Kansas City, MO’s Uptown Theater on July 1.

Particle keyboardist Steve Molitz has assembled a special band to pay tribute to Abbie Hoffman at the traveling Spiegelworld on August 24. While the venue is stationed at New York’s South Street Seaport, Molitz will celebrate the anniversary of Hoffman's famed 1967 crashing of the New York Stock Exchange with a group he is calling the Agents of Mayhem. The all-star ensemble also features the Disco Biscuits’ Jon Gutwillig, DJ Logic and Michael Travis and Jason Hann of the String Cheese Incident, among other special guests. According to Molitz, the evening promises “a late night of live improvised dance music, performance art, mischief and mayhem,” as well as opening sets by DJ Logic and the String Cheese offshoot EOTO.

Agents of Mayhem’s Spiegelworld debut is one of 50-odd shows scheduled to take place while the venue is docked in New York from August 6 - November 2. For its third, expanded season, Spiegelworld will feature not one but two performance tents: The Salon Perdu, the company’s vintage spiegeltent, and The Deluxe, marking the first time U.S. fans have seen two Belgian traveling venues side by side. Spiegelworld will also boast a version of the Bonnaroo staple Silent Disco, known as the Headphone Disco. Other shows of note include Dresden Dolls visionary Amanda Palmer (8/11), the Yard Dogs Road Show (9/21-22), The Benevento-Russo Duo and Travis Sullivan’s Bjorkestra (9/23), The Dodos (9/29), Antibalas Afrobeat Orchestra (10/5), Tim Fite & Mike Relm (10/7), Nellie McKay (10/14) and The Felice Brothers (11/2).
