Foo Fighters have teased that Nirvana is set to reunite this weekend for a performance at the band’s CalJam festival.

Yesterday evening, the rock giants posted two cryptic hints on Twitter that suggest a comeback performance could be on the cards.

The first came as they announced a screening of Joan Jett’s new documentary at the California festival. “CAN’T WAIT!! What else could we have up our sleeves???” Stay tuned….”, they wrote.

Jett, of course, famously joined Nirvana in 2014 as a backing singer for a one-time performance after their induction into the Rock and Roll Hall of Fame.

The second hint then came from that very performance – with Foo Fighters sharing footage on Twitter.

“This is a jam”, they wrote. The tweet was subsequently retweeted by Nirvana’s official account.

The rumors were given further substance by the festival’s line-up too. As well as ex-Nirvana members Dave Grohl and Pat Smear being in Foo Fighters, former Nirvana bassist Krist Novoselic is due to appear with his band, Giants In The Trees. 

They’ll also be joined on the line-up by Deer Tick, whose singer John McCauley performed in the 2014 Nirvana reunion.

Foo Fighters are yet to officially comment on the speculation.

Meanwhile, Dave Grohl recently played Nirvana’s ‘In Bloom’ for only the second time since Kurt Cobain’s death. In September, Grohl took to the stage to drum along to the seminal single from ‘Nevermind’ with Trombone Shorty at Los Angeles’ Voodoo Threauxdown Festival.
