Mazz - New Demeanour (Official Video)

Mazz Returns with Self-Reflective Banger ‘New Demeanour’.

UK rapper Mazz is back with New Demeanour—a moody, trapwave-laced track that marks a clear shift in mindset. Known for his gritty authenticity, Mazz turns the lens inward this time, unpacking growth, past mistakes, and the drive to move with more focus.

Backed by shadowy production from Palaze (whose credits include Pop Smoke, Lil Baby, NBA YoungBoy) and a razor-sharp mix from engineer Danger Sounds, New Demeanour doesn’t lose the edge that’s made Mazz one to watch—it just sharpens it.

Born in Cascais, Portugal and raised in Great Yarmouth, Mazz's music reflects the realities of growing up in under-resourced neighbourhoods. His lyrics pull from lived experience, blending trap and wave with a raw, introspective touch.

After making waves with tracks like Bad One, So Scandalous, and Keys to My Heart (which hit #58 on the UK iTunes Chart), New Demeanour feels like a step forward—both musically and personally.

The official video and audio are out now on all major platforms. Worth a listen if you like your music real, reflective, and rooted in the come-up.
