Horse Lords is an American avant-garde rock band from Baltimore that plays experimental music with elements of krautrock, post-punk, Appalachian and African musical traditions, polyrhythmia, arcane tunings and electronics. The band uses the just intonation tuning system favoured by avantgarde composers La Monte Young and James Tenney, so the musicians are playing hand-modified guitars with repositioned frets, re-tuned and customized by Owen Gardner.
