Matthew Joel is a typically unassuming folk-pop musician who moonlights as Bank Heist, making bright, beat-heavy electronic house “when the writing blocks hit and the rains of the fraser valley show no sign of stopping.” His first new track, “Sins of the Star Sapphire,” is a fine introduction to these restorative recordings, opening with a couple minutes of pure cabachon pop tones until a heavy dance beat shows up to round out the mix.
