I was using the word parallel in an e-mail and I never know where the 'll' goes when I spell that shit. Then I thought of X Parallel randomly.
His backstory (if I remember right) was that he was on a record label that wasn't supporting him, so he made this record with a concealed identity. Cool story... the single wasn't really all that: http://www.youtube.com/watch?v=cOBfdT8Kkxs
His website is now nonexistent and his Twitter handle is apparently owned by some Japanese person.
It seemed kinda gimmicky at the time and in hindsight, so I don't think it was anyone big. Anyone got the facts?
