Very few solo experimental projects lean heavily on the bass guitar, but Brooklyn's Russ Alderson does it mightily. Combining elements of noise, drone, and free improv, Xanthocephalus is Alderson's outlet for contemplation and destruction. sp. showcases so much of what is unique about this project, from the thoughtfully integrated field recordings, to the hypnotic low end drones, to the carefully controlled bursts of string shredding and feedback. For those who have yet to experience Alderson's work, this is a perfect entry point, and for those already familiar, this is another incredibly satisfying and intense expression of the enticing and dangerous ways of the wild.
