Mammatus’s second album The Coast Explodes straddles the line between psychedelia and hard rock while introducing more progressive aspects. The music is heavily influenced by both the power and complexity of the natural world and the ongoing battles of light and darkness. “Excellent Swordfight” continues the same story told on their debut’s “Dragon of the Deep.” “Pierce the Darkness” explores being a light in a dark world. “The Changing Wind” is a pipe-led psychedelic folk tune that could have been cited by Ghost’s Second Time Around and the shanga vibes of the forest in the Autumn. It unfurls into the title track which encapsulates the massive fury of the ocean.
