Rend Collective has never lacked imagination. From the bewildering array of children’s toys and handmade oddities they call instruments, to the wonderfully impractical scheme of recording a live album on the beach around a campfire, to the safety-defying audacity of shooting a music video on a fishing boat in the turbulent Irish Sea, this worship community has always pursued the colorful and unexpected. These folk-influenced troubadours delivered yet another prophetically sharp and sonically innovative message on their latest album, “As Family We Go.”
