Feldspar is an album by saxophonist and composer Matana Roberts, electric guitarist Sam Shalabi, and double bassist Nicolas Caloia.

Consisting of seven improvised tracks named after minerals, it was recorded on December 8, 2011, at Studio Hotel2Tango in Montreal, Canada, and was released in 2014 by the Canadian Tour de Bras label.

He noted the juxtaposition of Roberts' "earthy humanistic tone" with the "spasm-like dissonance" provided by Shalabi and Caloia.

"[4] The Free Jazz Collective's Martin Schray remarked: "The band mainly delves into harsh avant-garde idioms...

He stated: "Playing together as if they have done so for years, the three evolve a strategy that could almost be a fanciful vaudeville routine between an exuberant and an unruffled comedy team... A utilitarian rather than a trifling listen, concentrating on the sound production here will yield the same multi-faceted rewards that concentrated hard- rock mining does in other situations.
