The title is quite familiar to anyone with a medical background being the auditory transliteration in the old bygone days of the (normal) sounds the heart valves make when they open and close, called S1 and S2 more scientifically. Anyways, doctor knows best, great title-- archaically elegant, and the artwork is quite interesting as well, perhaps typical of the DIY / homemade crafts style of the early 80s LP covers we were made so familiar with in the frequenting record stores era.
Unlike the preceding instalment all the bands here are quite unknown-- luckily or suitably I should say, since most of the music here is quite experimental, approaching concrete-ness in its auditory impossibility.
The second track, by one Glass Philosophy is quite listenable however:
