Castalia by Mark Isham

Castalia (1988) is an album by the American trumpeter/synthesist Mark Isham. The title refers to the mythical spring Castalia on Mount Parnassus in Greece. This album features a larger ensemble of musicians than Isham's previous albums. Artists who performed on this album include guitarists David Torn and Peter Maunu, bassist Patrick O'Hearn, drummer Terry Bozzio and vocalist Gayle Moran. O'Hearn, Bozzio and Maunu were all in Isham's early band Group 87. Torn's atmospheric guitar work and O'Hearn's bass playing make a major contribution to the unique style of this album. Most of the pieces are in a long format, often beginning with subtle ambient textures and bursting into more active compositions. The song "In the Warmth of Your Night" is only available on CD and was available on Cassette. The album's cover artwork features illustrations of the Lissajous apparatus.
