A joke guys. I'm alluding to the fact (as I'm sure you both know damn well) that he took a career break (I was kidding by saying he "retired") after leaving Maiden & forming The Untouchables (> Psycho Motel) between 1990 - 1993. He didn't do anything (musically/professionally) in this period, did he?
His real "total" break was probably 1990 and 1991 and a part of 1992.
- gig with a certain band at Donington
- formation of The Untouchables and after that Skeleton Crew which became Psycho Motel. Not sure when he did exactly what but it took a while before the first Psycho Motel album was released: in 1995 (Japan only).
So perhaps another "break" in these years: 1993-1994, depending on when Adrian started writing new songs.
You're making this way too complicated. When did he leave Maiden, exactly? Was this not early 1990? And when did he form The Untouchables? I thought this was 1993? That's the break. Playing Donington hardly (as Wiki, I note, clarifies) counts as doing very much. He basically did nothing musically between leaving one & forming the other. Granted, I'm sure he was writing & picking his guitar up at home.
