IOSYS are currently at the event along with 7 of their newest releases. The most striking one is Ablitrosicks, a tribute album to... you guessed it, Albatrosicks. It looks like the characters created to represent the likeliness of Arm, Quim and Miko are gaining momentum; could a doujin anime be not so far-fetched? The CD has 5 brand-new and original songs along with a cover of 2004's "moshimoshi, bokudesu" from D.Watt's "22c" album. Speaking of which, he is the producer of the mini-album and a list of all contributors can be found on the IOSYS webstore.
[UPDATE] OTAKU-ELITE have just put up a webpage for the release which also features a full lyrics sheet and a sample MP3 of all tracks. All of the song titles and contributor names have also been translated to English. As I suspected, the whole thing is a big inside joke which pokes at existing Albatrosicks songs and themes. Not sure about the music's quality, but it should be interesting nonetheless.
Still on the subject of Albatrosicks, they will soon be playing a sold-out crowd on October 25 @ Studio Cube 326. This is, strangely enough, an afternoon show but that didn't stop the fans from buying tickets in droves. Hopefully some live footage will trickle into the intertubes but don't hold your breath. We haven't even seen much of Animelo 2008 at this point (despite the event being partially broadcast live on niconico), so I doubt this concert will get much more exposure.
