Q.E.D. (Terje Rypdal album)

Q.E.D. is a contemporary classical album by Norwegian jazz guitarist and composer Terje Rypdal recorded over two sessions in August and December 1991 and released on ECM in 1993. Rypdal is backed by the Borealis Ensemble conducted by Christian Eggen.

Reception
The AllMusic review by Paul Collins awarded the album 3 stars stating "Rypdal often alternates sections of great dissonance with near silence, or lonely sustained notes by just one or two instruments. It can have the sweeping starkness of a tracking shot over a fjord, but there's a certain coldness to it as well, and even confirmed fans of his jazz work may take a while to warm up to it."
