Slow down, now stop: what does this world need most of all? The answer is peace, and Los Angeles collective Build An Ark, formed in response to the xenophobic hysteria following 9/11, take a step in the right direction with this collection of brief but warm jazz jams. For those on a steady diet of electronics, this organic, largely acoustic session (led by producer Carlos Nino and vocalist Dwight Trible) takes a bit of adjusting to, but it’s well worth the effort, particularly on the stately “Vibes From the Tribe,” which features legendary trombonist Phil Ranelin. With a deep nod to Sun Ra, Build an Ark’s voices reason with the wilderness.
