Unpopular opinion: Bandcamp is overrated
████ ████ ███ ███ ██████on of how to find your entry point into the genre is something worth discussing practically.
The problem with most math rock recommendations is that they assume a certain amount of context that new listeners don't have. Recommending Don Caballero or Slint to someone who's never heard math rock is like recommending Coltrane to someone who's never heard jazz — technically correct but likely to produce the wrong impression.
The entry points that tend to work best are the records that have enough melodic content to give new listeners something to follow while they're developing their ear for the rhythmic complexity. Records that have clear emotional through-lines in addition to the formal complexity. Records that are beautiful as well as interesting.
The second criterion I'd use for a good entry point is duration: shorter albums work better for first exposure. An eight-track record that runs 35 minutes gives you enough to develop an initial relationship with the genre without overwhelming. Once someone has found the entry point, the more challenging material becomes accessible because they have a reference for what the music can do.
