The music found dates back to Van Halen’s earliest days at Sunset Sound in 1977 up until the recording of 1984, which was tracked at Eddie's 5150 Studios in 1983. In addition to the unreleased versions of "Hot for Teacher" and "Little Dreamer," there are also first-generation versions of long bootlegged demos such as “Bring on the Girls” and “Voodoo Queen," which later morphed into “Beautiful Girls” and “Mean Street,” respectively.
