Portland’s Fontanelle formed in 1998, following the dissolution of Jessamine, guitarist Rex Ritter and keyboardist Andy Brown’s previous music group. The duo added a revolving lineup that included drummers Michael Faeth and Mat Morgan, keyboardists Paul Dickow (also of Crisis and Technique) and Brian Foote (who, along with Morgan, can be area of the IDM duo Nudge), and guitarist Charlie Smyth. The group’s 2000 self-titled debut recording premiered by Kranky, Jessamine’s older home; likewise, Fontanelle’s refined, percolating sound constructed on the path of Jessamine’s last recording, Don’t Stay TOO MUCH TIME. F. adopted in springtime 2001 and emphasized the group’s digital leanings. Things had been extremely quiet for the Fontanelle front side for quite some time as the group’s players centered on different tasks for the better area of the oughts. In 2012, a complete 10 years since their last documented material, an extended edition of the group resurfaced with Supplement F, a fresh recording steeped in the audio and design of early-’70s electrical jazz-funk fusion.
