i found out about ae in 2013. :^)
i had somehow found out about boc, then afx, and every once in a while some autechre videos would be recommended for me on youtube, so i searched autechre on there.
the very first ae track i heard was FLeure.
after seeing that Warp had uploaded all of Exai, i decided that "fuck it, lets listen to all of it" and stopped listening when i got to jatevee C (i was really weirded out, i think)
then i listened to Clipper and thought "yknow this music is actually pretty good"
and then i started listening to the rest of their discography, and i guess that's how i found out about autechre
