I listened to a bit of the track you linked, but found it a bit challenging. I love Sigur Ros but they are much more ‘up beat’ and musical, compared to what I listened to for GSY!BE.
I’ve never listened to Mogwai, can someone suggest a good ‘representative’ track?
Mogwai has some stylistic range so it’s difficult to pick one song to be representative, but I think this version of “I’m Jim Morrison, I’m dead” gives a pretty good idea. It doesn’t really start till about 90 seconds in, so give it some time.
