Dark synthwave artist Black Challenger is out with his second album today. Without any lyrics, “Radiance” dwells in the night-cloaked rapture of electronic ether. There’s not a single moment of under-confidence in adventure here; the Challenger knows exactly where he’s going at all times, and the result is an enthralling expedition with each movement. For those that don’t know, Black Challenger is Will Bush of Immortal Girlfriend. It’s cool to watch Bush experiment with something a little different while retaining all the charm and wonder you love about the project with his brother Kevin.
