From the groups website:
"Thanks for making the Furthur community a great place to hang out, and for coming out to the shows. We'll all be keeping very busy over the foreseeable future, and it's time to let Furthur take a bow"

Below is a HQ video of the group covering a Grateful Dead song "Jack Straw" of course Furthur includes both Bob Weir and Phil Lesh from The Grateful Dead.
Some might be saddened that the group is calling it quits but many Deadheads are being very optimistic about what might come next. Since the Grateful Dead will be marking their 50th Anniversary soon. Below the group performs "Alligator:
Here the band performs Pink Floyd's "Time"
Fitting to close with "Time" since the group is calling it time to quit. Thanks for the songs, and thanks for keeping the spirit of the Grateful Dead I look forward to what comes next!
