Trying to classify the music made by Sky Creature isn’t easy. At times, you can hear the presence of thunderous punk rock in their DNA; at others, a much more ethereal sound comes to the foreground. The duo of Majel Connery and Matt Walsh have a new double EP, Childworld/Bear Mountain, out now, with a nationwide tour to follow. Each side of the EP shows a different element of the band’s style, and it makes for a haunting and immersive experience. I spoke with the duo about how the two records came about.
