Actress Ashley Judd hung out at the Gibson Lounge at Miner's Lodge at the Sundance Film Festival in Park City, Utah this week. She is seen here with the Gibson Music Rising guitar which has been produced to aid musicians affected by the hurricanes. All proceeds from the sales of the Music Rising Gibson Guitars go directly to the musicians.

Good Charlotte's Joel Madden spent some down time at the Gibson Lounge at Miner's Lodge at the Sundance Film Festival in Park City, Utah this week. Gibson Guitar has sponsored the exclusive jam sessions for all celebrities attending the festival throughout the week.

Actresses Maggie Gyllenhaal and Anne Heche stopped by the Gibson Lodge to autograph a Gibson guitar which will be auctioned off by MusiCares during Grammy Week. All proceeds from the auction will go to Music Rising, a campaign spearheaded by U2's the Edge to replace those lost or destroyed instruments in the wake of the hurricane disasters. Actor, producer, and director John Malkovich also put his autograph on the exclusive Gibson.

Actor Dennis Quaid rocked out at the Gibson Lodge during one of the daily, Gibson-hosted jam sessions. Oscar contender and actor Terrence Howard also jammed to an attentive crowd. Howard recently won rave reviews for his performance in the blockbusters Hustle and Flow and Crash.
