Since 1981, Wilfried Franzen and Thomas Grotz have been developing their own version of experimental pop music, which oscillates between song structures, noise, and psychedelic trance. Bass and keyboards form the instrumental substructure of the duo’s compositions, which are enriched with guitars, violin, piano, electronic percussions, and samples. After self-publishing various cassettes and cds, "Nachtwerk" is the first official release of SOLARIZE, which presents selected pieces from the years 1991 to 1998.
