Bob Weir

This is Bob Weir's initial solo release in more than a decade, and the first to feature all-new music in more than 30 years.

With the 50th anniversary of the Grateful Dead's formation coming up in 2015, Bob Weir is urging the group's surviving founding members to put aside their differences for some sort of commemorative event.

The two incidents may be unrelated, but five days after Bob Weir collapsed onstage during his band Furthur's set in Port Chester, N.Y., the group has canceled its headlining set at the BottleRock Napa Valley Festival in Napa, Calif. They were set to perform on May 9.

Bob and Grateful Dead bassist Phil Lesh have been touring under the name Furthur for a few years now and on Thursday, they were wrapping up a nine-show residency in Port Chester, New York. Bob was struggling throughout the night, and during "Unbroken Chain", he collapsed. The band's crew rushed out, helped him up and sat him in a chair so he could finish the song.

Late in Furthur's performance at the Capitol Theatre in Port Chester, N.Y. last night (April 25), former Grateful Dead guitarist Bob Weir collapsed onstage. The video is embedded above.
