It's an audience recording but the sound is really pretty good for 1967. Drums are clear and there is very little distortion. Jimmy Page can be heard playing the violin bow and there are taped sound effects which Page stated as being "the Staten Island Ferry, locomotives, shock sounds -- with textures from the bow".
I had a quick look round the net and can't find anything on this show or recording. It's really great stuff. And, as there are very few good quality late 60s live Yardbirds recordings around (and none featuring this track), it begs the really important question - Is there any more?
