It's been one of those weeks when it's overwhelmingly clear that we live in a post-grunge world.

It unofficially started last weekend when Temple of the Dog surprisingly reunited at Neil Young's annual Bridge School Benefit Concert (although all that really takes is for Chris Cornell to perform with Pearl Jam), but then Soundgarden -- perhaps even more surprisingly -- dropped a brand-new old song (explanation below) and Foo Fighters (who could only ever have come to exist in a post-grunge landscape) continue riding the waves of 'Sonic Highways.'

Even we here at Diffuser got caught up in all the flannel: check out our list of the 19 most influential grunge musicians and a look back at the seminal Seattle outfit Mother Love Bone. Of course, you should do that after listening to this week's Mandatory Music:

SOUNDGARDEN

'Storm’ from 'Echo of Miles: Scattered Tracks Across the Path'

If the new Soundgarden song, 'Storm,' sounds a lot like old Soundgarden, there's a pretty good reason for that. The grunge godfathers unceremoniously unveiled the foreboding and droning track earlier this week, then waited a day to tell everyone it's actually a newly recorded version of a 30-year-old demo. 'Storm' will be on Soundgarden's long-awaited but just-announced B-sides and rarities compilation, 'Echo of Miles: Scattered Tracks Across the Path.' Listen to the song and see if you can resist the immediate urge to tape something off the radio.

FOO FIGHTERS

'The Feast and the Famine’ from 'Sonic Highways'

If you've been following the Foo Fighters extensive pre-release push for their upcoming eighth album, 'Sonic Highways,' or have just been watching their HBO documentary series of the same name, you're abundantly aware of the album's concept: Dave Grohl and the guys recorded each song at a different iconic studio in eight different American musical meccas. For the angular and driving track, 'The Feast and the Famine,' the Foos traveled to Grohl's hometown region of Washington, D.C., to record at the unofficial headquarters of Dischord Records -- Inner Ear Studios.

THE DEAD WEATHER

'Buzzkill(er)’

Jack White probably writes more songs before breakfast than most songwriters can pen in a month. Currently supporting his second solo album, 'Lazaretto' (and recently dropping by Yale to have an academic discussion about the history of landmark label Paramount Records), White and one of his side-projects, the Alison Mosshart-fronted supergroup the Dead Weather, have been releasing two-song singles leading up to the release of their third album. They just dropped the latest, the raucous 'Buzzkill(er),' and it's guaranteed to saw right through even the worst of bad days.

BELLE AND SEBASTIAN

'The Party Line’ from 'Girls In Peacetime Want to Dance'

Belle and Sebastian frontman Stuart Murdoch is apparently doing his best to be the Bo Jackson of indie rock. Just a month after 'God Help the Girl,' the critically acclaimed movie he wrote and directed starring Emily Browning premiered stateside, Belle and Sebastian have shared the first song from their upcoming ninth album, 'Girls In Peacetime Want to Dance.' (Seems like Murdoch must have girls on his mind.) 'The Party Line' is an upbeat, EDM-inspired number complete with funky bass and cow bell. Look for the album in January.

CIRCA SURVIVE

'Schema’ from 'Descensus'

After a decade purveying their often copied but never replicated brand of progressive post-hardcore and surviving a run through the major label ringer, Philadelphia-based Circa Survive are set to release their fifth album, 'Descensus,' in November. Although frontman Anthony Green has had a well-documented battle with the demons inside him, in the video for the pulsing lead single, 'Schema,' he faces off in a boxing ring against a much more tangible (albeit surreal) opponent.
