Last night, Acoustic-4-A-Cure IV took over the Fillmore in San Francisco for a night of music and charity. Metallica’s James Hetfield and Sammy Hagar launched Acoustic-4-A-Cure back in 2014 to fund research efforts for San Francisco’s Benioff Children’s Hospital, the Pediatric Cancer Program at the University of California. This year’s benefit concert featured Bob Weir, Sammy Hagar, Vic Johnson, Sarah McLauchlan, Steve Vair, Pat Benatar & Neil Giraldo, Don Felder, Mick Fleetwood, and Dave Grohl (who sat in for James Hetfield as he is away on tour). The artists played through acoustic sets, delivering once-in-a-lifetime musical moments, collaborations, and more.

Dave Grohl, Taylor Hawkins, and Rami Jaffee debuted a new Foo Fighters song, called “The Sky Is A Neighborhood,” after playing through Foo favorites “Everlong,” “My Hero” and “Times Like These.” The song marks the band’s first new official release since 2012’s Sonic Highways and the 2015 “surprise” EP Saint Cecilia. With an international tour ahead of them, this new rock ballad is a positive indicator of the album the band is reportedly spending the year working on.

Another one of the night’s highlights was when Grateful Dead guitarist Bob Weir teamed up with drummer Mick Fleetwood, guitarist Steve Vai, and bassist Ruth Davies to perform “Easy To Slip” by Little Feat, his original “Only A River,” as well as Dead classics “The Other One” and “Loose Lucy,” which Sammy Hagar joined in for.
