One Part Per Million

One Part Per Million is an indie rock band that has multiple forms. We have been a 2, 3 and 4 piece band (currently 2 or 3). What makes us different is the use of clarinet in an upbeat rock setting.The core members are Brian Callaghan (guitar, keys, vocals, etc.) and Martha Monnen (vocals, clarinet, keys).Our music is complex in spirit and covers a wide range of subjects. Our passion comes out in the music. We have a strong chemistry due mostly to the fact that we are romantically involved.
