Swiss experimental rock quartet Sonar (whose name is a portmanteau of "sonic" and "architecture") comprise guitarists Stephan Thelen and Bernhard Wagner, bassist Christian Kuntner, and drummer Manuel Pasquinelli. The bandmembers bring an array of talents uniquely suited to creating Sonar's precise and rhythmically complex yet spacious and streamlined post-minimalist sound, harmonically idiosyncratic with the guitars and bass tuned in tritones (an interval given the Latin name diabolus in musica -- the devil in music -- during medieval times). The California-born Thelen is a strong admirer of the early- to mid-'70s (Starless and Bible Black) and early- to mid-'80s (Discipline) editions of King Crimson, and participated with the Venezuela-born Wagner in Robert Fripp's Guitar Craft seminars in the '90s. Thelen (Sonar's principal composer) also studied classical guitar, and he earned a Ph.D. in mathematics from the University of Zurich. As a solo artist, Wagner performs and records using innovative live looping processes; he is also a software engineer. Kuntner and Pasquinelli are participants in a wide variety of bands and projects, and both are former students at the University of Arts in Bern.
