Kurt Cobain: We were just amazed we were putting out a record. We were, and are, still learning. But we've never cared much for professionalism as long as the energy was there. Like our live shows: We're out of tune and use a lot of feedback. That's not on purpose or because we don't care, we're just musically and rhythmically retarded and we play so hard that we can't tune our guitars fast enough.
