The Baltimore rapper Dan Keech — who has recorded as Height, Height With Friends, and Height Keech — has been a staple of his city’s DIY scene for something like 15 years now. Two years ago, he released his Unending Blaze, Volume 1 EP, the first entry in a planned series. He ended up abandoning that plan and reworking the whole EP series into a new self-produced album called Mind Moves The Mountain. And now he’s shared the early track “Dead Rider Ride On,” a quick burst of moody intensity. Listen to it below.
