San Francisco-based Blue Sky Black Death took its name from a skydiving term referencing how beautiful everything looks before you splat into the ground. If you tone down the black death a notch, it’s a good metaphor for the band’s sound as well. BSBD starts with simple drum loops and slowly layers in keys, strings and breathy pads, for a chill, hip-hop sound as light and clear as air, but with a beat that steadily chugs onward.
