According to The Pulse of Radio, FOO FIGHTERS‘ official Twitter account posted two cryptic tweets regarding this upcoming weekend’s Cal Jam festival, which is set to take place in San Bernardino, California. First, in a tweet announcing a screening of Joan Jett‘s new documentary, FOO FIGHTERS responded by tweeting: “CAN’T WAIT!!!! What else could we have up our sleeves???” Stay tuned…”

Hours later, FOO FIGHTERS shared footage from NIRVANA‘s Rock And Roll Hall Of Fame afterparty set, which took place following the band’s induction in 2014. That tweet included the caption, “This is a Jam @caljamfest #CalJam18,” and it was retweeted by NIRVANA‘s verified Twitter account.

What could it mean? Well, all three surviving NIRVANA members will be present at Cal Jam. Dave Grohl and Pat Smear play together in FOO FIGHTERS, while Krist Novoselic is scheduled to appear with his current band, GIANTS IN THE TREES.

Also at the festival are two of the vocalists from that afterparty show: Jett and John McAuley of the band DEER TICK. McAuley is also featured in footage tweeted by both bands’ accounts, which shows “Serve The Servants” played backwards.

Could the surviving members of NIRVANA be planning to recreate that 2014 performance at Cal Jam this weekend?
