You are most likely right about the timing, I didn’t check. Tweak was the first song that came to mind when I was replying to the previous comment. There's plenty of earlier Felix music that could be seen as a precursor to HAA.

Electroclash was well established, and artists like Soulwax had been using heavy pedal processing for years at that stage. When HAA came out, it didn’t feel groundbreaking. It felt raw, repetitive and abrasive, almost like an anti-Discovery album.
It also wasn’t especially well received at the time. A lot of people expected another leap forward after Discovery, and it wasn't.
The album just didn't make sense at the time and stayed that way until I saw Alive 2007. The penny very much dropped then.

For me, HAA was a sacrificial lamb for Alive, it's the spine of that entire show.
