Phil Lesh's two-night NYC-area run has turned into three nights. After playing Central Park SummerStage on 9/5 (tickets) and The Capitol Theatre on 9/6 (tickets), the Grateful Dead bassist will headline a voter participation benefit concert at Harlem's historic Apollo Theatre on September 7. At all three shows, he'll be joined by his backing band, The Terrapin Family Band, and guest vocalist Nicki Bluhm. He'll also have Eric Krasno at the first two shows.

The Apollo show, which is billed as Don’t Tell Me This Country Ain’t Go No Heart: A Benefit for Voter Participation, also features veteran Brooklyn rapper Talib Kweli and funk musician Robert Randolph (who's collaborated with Phil before). Tickets are on presale now and the public on-sale starts Friday (8/17) at noon, and proceeds benefit Headcount.

It's the first time Phil (or any Grateful Dead member) will be playing The Apollo. "Playing the Apollo the first time is both an honor for me personally and something I can do to help support as many people voting in the Midterms and beyond. I can’t wait for September 7th … and for November 6th," Phil tells Rolling Stone.

While Phil is on the East Coast, he'll play Philly's Festival Pier at Penny's Landing on 9/9 (tickets). His only other upcoming show at the moment is the 10/21 Hollywood Bowl stop of Willie Nelson's Outlaw Music Festival tour.

As for Phil's former Grateful Dead bandmates Bob Weir, Mickey Hart, and Bill Kreutzmann, their band Dead & Company just announced the second annual Playing in the Sand. Before that, Bobby's trio Wolf Bros will be playing Dead songs on tour.
