"Lados B" is a deep dive into the high-level spontaneous music made by Villarreal, Parker, and Butterss across those two days in 2020. Villarreal is heard leading the group through various rhythmic modes and structures for improvisation - flow as informed by the Latin funk of Fania Records as it is by the otherworldly humanity trance of Brain Records - while Parker and Butterss draw on their extensive experience playing free together (as heard on their ETA IVtet LPs) to build harmonic buoys for their spontaneous melodicism. The result is a beautifully vivid illustration of context, creativity, and collective composition from a particularly rich moment in history.
