Although working-class boys' disengagement with education continues to be a major public concern, the focus of educational research has been on anti-school, hyper-masculine so-called "laddish" masculinities and their salience within learner identities. What tend to be forgotten are the areas in which low-achieving boys actively engage and succeed in their learning and what these successes mean for their identity construction. This article shows how learning practices manifest themselves in extracurricular peer subcultures by presenting the findings of two related musical activities, DJ-ing and MC-ing. In this music-making, secondary school boys in the Northeast of England showed themselves to be capable of high levels of engagement, enthusiasm and success despite generally being considered low achieving and highly disaffected. This small case study based on semistructured interviews aimed to explore how boys aged 14-16 years enact their passion through creative agency and expressive cultural processes. (Contains 3 notes.)
