"Swampstock 2006," Tim McGraw [ tickets ]'s 11th celebrity concert and softball game, is set for Oct. 7 at the Tim McGraw Sports Complex in his hometown of Rayville, LA.

Guests scheduled to join McGraw and his wife, Faith Hill [ tickets ], at the event include Martina McBride, Hot Apple Pie, Lori McKenna, Redneck Rockstars and Catherine Raney.

Tickets go on sale Friday (9/15) via Ticketmaster. (Ticketmaster is LiveDaily's parent company); net proceeds will benefit local organizations through McGraw and Hill's Neighbor's Keeper Foundation.

Fellow guitar wizards Steve Vai [ tickets ] and Joe Satriani [ tickets ], along with unannounced guests, will play a Sept. 30 benefit show at West Hollywood, CA's House of Blues to benefit ailing music-industry veteran Cliff Cultreri, who is currently Vice President of A&R at KOCH Records.

Cultreri--who "discovered" Satriani and Vai, among other artists, while working at Relativity Records--"is currently suffering from a host of Auto-Immune and Connective-Tissue disorders that are attacking his immune system, a one in 100 million occurrence that causes severe pain and physical problems," according to a press release.

"Cliff has been a musical force and guiding light in my career and my life for two decades," Satriani said in press statement. "He introduced and championed my music to the music business. He is a dear friend and musical ally and quite the guitar player himself. Steve and I wanted to help Cliff and the idea of a show in LA with other members of the guitar community seemed to be the obvious way to celebrate and help him."

Sean Lennon [ tickets ], the son of John Lennon and Yoko Ono, is set to issue a new album titled "Friendly Fire" on Oct. 3.

Lennon has also produced a short film for each of the album's tracks, directed by Michele Civetta.
