Cheap Trick from a Japanese TV broadcast of the "Live At Budokan" shows.
Cheap Trick-Speak Now Or Forever Hold Your Peace (Live At Budokan).mov
Buy the 1st Cheap Trick LP. It's the one Nirvana based their whole sound on.
Update: We have a quibbler in the comments already. Here's the quote for you unbelievers, from your God "…We sound just like Cheap Trick, only the guitars are louder"- Kurt Cobain, Rolling Stone magazine." They also ripped off the Pixies if you hadn't noticed. And here's MP3.com's Nirvana similar artists page that lists Cheap Trick. Oh yeah, they're at the TOP of the list of Nirvana influences on AllMusic.com.
