Here's a recording from Van Halen's Monsters of Rock performance in Stockholm, Sweden, from August 25, 1984.
The audience recording includes an epic 13-minute solo from Eddie Van Halen and is one of the better-sounding recordings from that particular show.
The Van Halen News Desk points out that Ed’s solo “contains a killer blues jam. During the solo, you’ll recognize a certain guitar riff that was later turned into a complete song [Van Halen] released on a later album. Can you spot it?”
The solo starts at 55:00.
