First room is the debut solo album from microtonal tuba player and composer Martin Taxt. The album is the first in a series of works investigating possible relations between architecture and music. First room is a tribute to the Japanese tearoom and the tatami mat. The floor plan as shown on the cover has been used as a foundation for the musical score, performed by Inga Margrete Aas on viola da gamba and double bass, and Martin Taxt on microtonal tuba and sine waves. The album is an intricate mix between a studio recording and a live performance, both recorded in the same room over two days. The live musicians are often shadowing the recorded material, and with subtle changes in pitch and timbre the combined sound of live and recorded sound create an ambiguous and at times fragile sound. The performance included live video from visual artist Kjell Bjørgeengen.
