Trombonist Mike Svoboda's Wergo release entitled Da Lontano (from a distance) surveys rarely heard works written by four heroes of new music that are 'outside' of the ordained list of masterworks by these composers. Each has an element of indeterminacy, which allows Svoboda to place a personal stamp on the performances. Scelsi said he received the music for his Mantram - Canto anonimo from other spheres, merely acting as an intermediary between two worlds. For Solo for Sliding Trombone, excerpted from Cage's Piano Concerto, Svoboda devised a version for eight trombones which he plays all by himself. Signal zur Invasion I is excerpted from Stockhausen's opera Dienstag aus Licht. It consists of 126 fanfares from the opera. In Nono's Post-prae-ludium per Donau, the sound of Svoboda's tuba is multiplied and rearranged by electronic musician Holger Stenschke to create a unique spatial polyphony.
