In sure to make you feel old news, Nirvana’s seminal 1991 album Nevermind turned 20 this month – September 24th, to be exact. This means that Nevermind has probably grown out of his Nirvana stage by now.

All kidding aside, Nevermind was and still is a great album that marked a shift in music and culture. It was often emulated, but never really matched. Kurt Cobain and crew had a profound influence on the youth of the day and the music still continues to hold a special place in a lot of people’s hearts.

We will forgive them for giving birth to the mid-90s.

In honor of Nevermind‘s birthday, VEVO is streaming a never-before-seen 1991 concert. “Live at the Paramount” features classics like “Smells Like Teen Spirit,” “Polly,” “Breed,” “Lithium” and a cover of the Vaselines’ “Jesus Wants Me For a Sunbeam.”

The concert will be available on-demand for 24 hours, and it started at 12 pm EST Tuesday. That mean’s you’ve got until Noon EST Wednesday to watch it. From VEVO’s blog on Monday:

It’s been two decades since bleached blonde hair, flannel and teen spirit were paired in such a way that they’ll forever remain symbols of Nirvana‘s slice in time. To celebrate the 20th anniversary of the band’s ground-breaking album Nevermind, we’re bringing you an exclusive commercial-free, on-demand airing of the band’s 1991 concert, Live at Paramount. Beginning tomorrow at 12 pm ET/5pm GMT, you can watch Kurt, Krist and Dave rock out in high-definition from your laptop, TV, iPad, or even from the VEVO app, right on your phone, for 24 straight hours.

Since it was originally a Halloween concert, VEVO will stream it again on Halloween for another 24 hours.
