There is more than one artist called Chamber. 1) Chamber Bio:
1998: Viennese singer/songwriter Marcus Testory unites contrabass, cello, viola and violins with his guitars and chant to Chamber - L' Orchestre De Chambre Noir.
" ...Bittersweet, just like Leonhard Cohen or Nick Cave, the sound of this orchestra transmits a magical feel within it’s songs full of emotion, desire and a breeze of black humor..."
