John Fahey - Requia (1967)

John Fahey is an American Guitarist, famed for blending a series of styles in order to create "American Primitivism", and really re-popularized the guitar as a Concert Instrument rather than just fodder for ever unimaginative blues and rock'n'roll band, and in my mind, is one of the most interesting musical figures of the later part of the 20th century.

Radicalfashion- Odori (2007)

Under the name Radicalfashion, Japanese pianist/programmer Hirohito Ihara crafted a special album that was simultaneously both unassuming and wildly inventive.  Combining glitch, neo-classical elements, simplistic piano, and musique concrete, Odori is a quick 30 minutes that floats from one idea to another, effortlessly shifting from carefree to contemplative to profound. 

Graham Lambkin - Salmon Run (2007)

Graham Lambkin is an experimental musician from the UK, famed for having worked with Jason Lescalleet, and on his 2007 album Salmon Run, he has crafted what is, in my opinion, one of the best Musique Concrète albums of all time.
