The Catler Brothers play instrumental music in the tuning system known as Just Intonation, using refretted guitars with 64-tones to the octave as well as fretless guitar and bass. The music uses notes, chords, and melodies never heard before. The Catler Brothers have been playing together for many years, and their telepathic interplay is evident on recordings like 'Crash Landing'. They have toured the world with legendary composer La Monte Young in the Forever Bad Blues Band and have appeared in many festivals in Europe and the U.S.
