Akima & Neos appears to have been a band led by Akima, not just a solo pseudonym. This
interview with Akima refers to the band's drummer, Haruhiko Oshima (大島治彦), whose own
site lists a band line-up with the names of an additional guitarist, bassist and backup singers, at least during his time in it. No way to know, of course, whether any of them played on this album's 2 songs. I've never figured out who "Aja" is either (and I've tried), but is there a particular reason to even think it's the Aja who has an entry here? I don't see anything that would suggest it's the same person.
