It was a different time, they were caught up in the blues trends by the sounds of it, and hadn't found their own sound; also sounds like they hadn't practiced much as a band...very garage band-ish sounding. I found it interesting knowing what was to come from them, to hear how it all started. Nothing special here as you said, but they went on to create a genreIn general I think it is crap. But there is some very interesting parts done by everyone. Some of the phrasing in the guitar sounded very familiar.
Sounds like a Stratocaster and fuzz box.
