*2022 Stock.* Solo includes new recordings of vintage-era variable-form solo chamber works involving shortwave radio or delay processing. A unique version of Solo (accompanied by excerpts from Hymnen Region 2) was previously recorded by trombonist Vinko Globokar for Deutsche-Grammaphon, but this is its first proper appearance on the Stockhausen label. Earlier electro-acoustic noise versions of Spiral can be found on The Stockhausen Edition no. 15. Both of these works feature an element of performer improvisation in reaction to the score elements. - Stockhausenspace.blogspot.com
