After a number of succesful years during the early 60s in New York, where he recorded with, among others, Coltrane and Shepp, Tchicai returned to his native Denmark and formed the group Cadentia Nova Danica. This band made two recordings, of which this was the first. The band was enlarged considerably for the second, Afrodisiaca.
The line up (see back cover in scans) was mainly comprised of Danish musicians, none of whom, to my knowledge, subsequently became known outside Scandinavia (at least in the jazz field, although I gather the second altoist, Vogel, became well-known in progressive rock). The music on the recording, which was done live in a hall in Aarhus, Denmark, has a strong Scandinavian feel to it (not surprisingly). Tchicai plays some nice solos, but it is the ensemble that makes this a terrific recording.
