Erik Mikael Karlsson (S), born 1967, studied composition and computer music at EMS with Tamas Ungvary among others. Karlsson has been awarded several prestigious international prizes for his music such as EBU/UNESCO Rostrum prizes both 1992 (selected work) and 1994 (recommended work) and two first prizes in the Bourges' Grand Prix Internationaux in France in 1993 and an honorary mention in 1993 Prix Ars Electronica.

It is not possible to describe a piece with just a few words. Especially not when the piece has many different ideas as approaches, rather than just one. Some of the compositional ideas run parallel, some arise fragmentarily, some are tied together and some exist independant from the rest. Dialogues and contrasts, contacts and disclaimings embrace each other between the real and the imaginary, where gestures, poetry, timbre and acoustics create an unspeakable longing for beauty. The attentive listener can also find some bars from Rodgers' and Hart's wonderful tune "The Lady is a Tramp".

"Interiors and Interplay" was produced at EMS and Swedish Broadcasting Corporation in Stockholm between February and June 1994. The sound material consists of different kinds of concrete material, processed voices from a soprano and tenor (Swedish Radio Choir) and a synthetic material generated with IRCAM's Chant-program, but also some material from my period in Berlin in 1992-93. A vast number of sounds were processed with software by Paul Pignon (Time Pitch Mapping, Giant Fourier Transform, Running Convolution).
