‘Heart Under’, Just Mustard’s second album and first for Partisan Records, is an album that asks you to forget what you know. At every turn, this remarkable record reconfigures and stretches the ideas and ambition of a rock band, and turns a year of lockdown and personal struggles into a breathtaking artistic statement.

The music the five friends from Dundalk, Ireland make is strikingly untraditional. Though to look at them, it appears that the band are a five-piece with uniform make-up of a vocalist, two guitarists, a bassist and a drummer, not a single one of them utilizes their instrument in a confined or regular fashion. Guitarists David Noonan and Mete Kalyoncuoglu make their six-strings shriek and wail, the sounds produced sounding like everything from whirring machinery to horror movie monsters. On the introduction to the dark and dangerous ‘Seed’, it’s half-way to being a techno beat. On a great deal of the album, this harshness is juxtaposed by watery, swelling guitar chords that add a dreamy texture to the record alongside the more aggressive, industrial tones. “This is just a piece of wood with some metal strings attached – you can do whatever you want with it,” Mete says of his approach to his instrument.
