Maybe he tried to give a broad panel of electronic music. Autechre does have its own universe, I didn't listen more than 2 minutes in because the link loaded slowly and 2h made me skip.
It's the whole record that's why it's 2h. If you have Spotify you can listen to them piecemeal. I recommend Tri Repetae. It's my favorite record of them. It's not for everyone, and it's definitely not dance music. To me, they managed to make music that is a strange and poignant mixture of the cold and robotic and warm and human. It's electronic music at its best, something that can't really be achieved in other genres.
