Pearl Jam guitarist Mike McCready hosted the first-ever Peak To Sky Music Festival in Big Sky, Montana over the weekend (July 6th and 7th), a two-day event featuring performances from McCready’s visual and arts project Infinite Color & Sound, Brandi Carlile and others.

The festivities were capped with an all-star super jam consisting of McCready, Carlile, Guns N’ Roses bassist Duff McKagan, Red Hot Chili Peppers drummer Chad Smith and guitarist Josh Klinghoffer, and Foo Fighters drummer Taylor Hawkins.

Among the songs the supergroup performed were Led Zeppelin’s "Moby Dick," "Good Times, Bad Times" and "Dazed And Confused," Van Halen’s "Eruption," Aerosmith’s "Sweet Emotion," Prince’s "Purple Rain," David Bowie and Queen’s "Under Pressure," Bowie’s "Moonage Daydream" and "Ziggy Stardust," plus others.

Foo Fighters are doing scattered live dates throughout the summer, while both Pearl Jam and the Chili Peppers are off the road and reportedly working on new albums.
