Nearly 24 years ago, recording engineer Gert Palmcrantz, acting on behalf of the Proprius label of Sweden, ran a few microphone cables from the stage of the "Stampen" in Stockholm back into the kitchen of the club, plugged them into his recorder and started taping. (Referring to several sources, we find that these recordings were actually made over two nights in December, 1976, although it is unclear whether the recording dates were 12/6 & 7 or 12/14 & 15: different sources list different dates.)
Mr. Palmcrantz's efforts resulted in the near-legendary-among-audiophiles live recording, Jazz at the Pawnshop, a 2-LP set (PROP7778/9), released in 1977. The recording features a quintet headed by Arne Domnerus on alto sax and clarinet, backed up by Bengt Hallberg on piano, Lars Erstrand on vibes, Georg Riedel on bass (acoustic), and Egil Johansen on drums.
