Chicago’s Radiant Devices conjure dark, hypnotic, evocative (and lengthy) recordings. The band leans toward eerie, atmospheric intros from which Mojdeh’s impressive voice emerges to add precious moments of dramatic adornment. In their best song, “Drowning Chain,” we hear a likeness to Evanescence, fronted by Amy Lee. The key difference is that Mojdeh is not her band’s focal point. They opt instead for an ensemble approach and it leads to some ponderous stretches (the 9-minute “Dirty”) that, despite imaginative instrumentation and sonic effects, give the impression that the music is somehow incomplete without an equally imaginative eye-candy presentation.
