Project 86 frontman Andrew Schwab doesn’t mind stepping out of his comfort zone to test the sonic boundaries between the brutal and gentle. Wait for the Siren finds his group weathering the departure of guitarist/keyboardist Randy Torres with the help of such notables as Living Sacrifice vocalist Bruce Fitzhugh, Korn/Love and Death mainstay Brian “Head” Welch, and Disciple guitarist Andrew Welch. The album reflects this eclectic lineup with a creative interweaving of muscle-flexing rock, frenetic hardcore, and evocative acoustic folk sounds. The Celtic-tinged “Ghosts of the Easter Rising” is especially striking in its use of uilleann pipes and hammered dulcimer. Punk aggression meets prog-rock ambition on the defiant “Fall, Goliath, Fall” and the spacy, Pink Floyd–esque “Blood Moon.” Faith remains the consistent focus, whether the message reflects Old Testament scripture (“SOTS,” “Above the Desert Sea”) or the coming days of apocalyptic conflict (“Take the Hill”). “Defector” stands out for its desperate plea for God’s grace. Wait for the Siren boasts the sort of complex musical architecture and dense lyrical mythology that hits hard, burns deep, and feeds the Spirit.
