how would to classify this type of music?
 

Hey everyone new to the forum, and was looking for some help, I saw this group last night here in Indianapolis, and was hoping to get some related artists or similar types of artists. Search Circle's Corner on soundcloud, I think they have a couple things posted

They're post-rock. Check out groups like Godspeed You! Black Emperor, Sigur Ros, Mogwai, Explosions in the Sky or Tortoise if you want to hear similar stuff.
