What makes Chambers work is that it doesn’t feel like an experiment for the sake of it. The processing serves the music, not the other way around. It’s the kind of release that sneaks up on you, not flashy, but it sticks. By the time it’s over, you realize there’s more going on than you initially thought. This is a strong showing from Ruben, and for a limited run of 30 cassettes, it punches well above its weight.
