Hekla is a rare virtuosic player of the theremin, a notoriously difficult electronic instrument, joining a miniscule group of musicians in mastery of its esoteric, light-controlled frequencies. Classically informed, her playing covers an enormous range, from skittering birdsong of chirrups and chirps to tectonic sub-bass. Her fans in the wider music community - PJ Harvey, for example - describe her style alongside musicians such as Colleen, Julia Holter or the late Jóhann Jóhannsson.

A Berlin-residing Icelander, Hekla’s sparse, delicate, fractal music exists within these two worlds: dark and magical as Iceland’s permanight folklore; and (though beatless) as deeply sonic and intense as Berlin’s electronic scene. A long-term scholar of solo theremin, Hekla (shortened from her own name Hekla Magnúsdóttir) uses her instrument as an otherworldly and highly evocative Siren-call. A spectral, wailing, howling, lamenting yearning second-voice that underpins a soft vocal delivery, as if her studio had been haunted with a chorus of ghostly backing singers.
