I open a new thread since the oroginal one is older than 365 days, therefore i can't reply there :)
According to Wikipedia, the oldest album to feature an e-mail address (not an URL) is Billy Idol's Cyberpunk., released in June 1993.
I really loved this album ,and i still love it...for me is one of the most UNDERRATED albums ever made by a big artist ....his career basically flopped since there...maybe the thematics were ahed of the time...maybe his look was totally different from his usual 80s style...who knows.
Quoting Wikipedia, Cyberpunk was the first album which listed the e-mail address of the artist in ments and within the album booklet. Penn Jillette claimed to have sent a request for comment from Idol to the address, but received no response. The address, [email protected], is now inactive.
Notoriously, Cyberpunk was also the first multimedia floppy disk included as a special feature for an album, here's the Discogs realease Cyberpunk
