For a peck of audiences in Australia over the past couple of years, Bonnie Stewart (Ireland) has been one of those subtly transcendent artists. Her lilting vocals float over gentle peaks of acoustic and electronic instruments, layered ethereally into what may be a moderately enchanted loop pedal. Under the spell of thrumming guitar, Stewart renders her arrangements with a fidelity of performance that seems to amplify an almost spectral presence. This is Bonniesongs. She’ll play loudly whilst making you ridiculously aware of silence and then go some way to reminding you how music is at its most basic, mere vibration moving through air, occupying the same molecular space as the incorporeal.
