There weren't a lot of people that saw Van Halen perform back in 1975. But, now that a rare recording has surfaced online, you can hear what Eddie, Michael, David and Alex sounded like way before their legendary debut album.

The description on the YouTube channel were the two song set appeared gives a few more details.

Here's Van Halen mega-rare two-song "Rock Opera" live at Pasadena HS on April 25, 1975: "Eyes of the Night - Forced Entry."

Be warned that the audio is less than spectacular quality, but considering this is 1975 we're talking about, not gonna complain. It gets better around the 4:33 mark of the video, so bear with it and you'll be rewarded with some very vintage early Eddie riffs.
