Tuner has released six albums and also functions as a production team, having produced and arranged records for Toyah, Moonbound and Chrysta Bell and as remixers (having contributed to Steven Wilson's Insurgentes Rmxs).
Markus Reuter also had King Crimson connections, having been a former student of Robert Fripp's Guitar Craft and subsequently gone on to work with the Craft-inspired Europa String Choir.
Trey gunn, being a mutual aquaintence, introduced Mastelotto and Reuter to each other who exchanged CDs.
[5] Tuner's music is best classified as experimental art-rock with a strong element of textural looping.
Reuter has described their music as "overlapping and independently shifting rhythmic patterns combined with beautiful melodies" and as featuring ideas which can be "permutated endlessly."
