They've got the psychedelic rock staples of drums, guitar, and bass, but there are some twists. On top of that rhythm section, they throw in a charango and violin to create counter-melodies and build on the harmonic framework. They also have an innate talent for changing up the verse-chorus structure with jams that manage to maintain and even increase the listener's interest. In these jam sections, they'll often mess around with effects or switch up the instrumentation in order to create new sonic textures within the piece, which adds the maturity of their sound.
