The Neurohumors are a constantly re-arranged combination of San Francisco-based musicians that specialize in largely improvisational rock, jazz, progressive and ambient styles. Employing open-ended "launch pads", the band is known for journeying through a variety of moods and genres within a single, contiguous piece of music. Jams may exceed 25 minutes, during the course of which trance-like modes and mellow psychedelia give forth to polyrhythmic climaxes, danceable grooves and/or sophisticated jazz punctuations. New or accidental audience members find themselves appreciating the ride despite what they might usually look for in music; veteran Neurohumors fans know that the ever-changing line-up means something new every time.
