Not much. He started selling the album in 2005, but his old website went down not too long after. Here's an archived version that mentions the album:
http://replay.waybackmachine.org/200...oedarwish.net/. The sale page unfortunately wasn't archived, but that page mentions it was sold through "Independent Downloads," so it may have actually been a purely digital release. I don't recall.
"The Ken Song (ver. 2)" (also known as "The Ken Song V2," "The Ken Song (Version 2)," etc., I'm not sure which is canonical) is a rerecorded and slightly rearranged version of his original "The Ken Song," which was posted on OC ReMix:
http://ocremix.org/remix/OCR01266/. He liked it more at the time, but he uses the first version on his current MySpace page, so maybe he's changed his mind? Haven't talked to him in years.
He uploaded "Wake Up" (track 3) to MP3 Unsigned, and it's still up:
