Hmm, judgement’s off, gotta go with my first thought .. which would be Death Valley 69, it blew me away first time I heard it, and still does. But then again, that goes for a lot of the others choices too.
i’d have to go with "I love her all the time" off bad moon rising because it has the most original guitar work which is what i love about sonic youth, if you ever geta chance there is akick ass version of it on the ’91 the year punk broke video
