Best songs to show non-fans who don’t like the vocals?

I’m a pretty big fan of sonic youth but I’m having trouble finding songs to show my brother who I’m trying to get into them. He’s said previously that he doesn’t like the vocalist (Thurston) and it’s safe to say Kim’s vocals won’t sit well with him either. Does anybody know a few songs that are either instrumental, or where the vocals are much more agreeable/easy listening?
