Here's a dream double-bill for Americana enthusiasts who despise the enclosures of that term. Nashville guitarist William Tyler first made his career and reputation by backing Lambchop and Silver Jews, but it's his solo guitar output—namely, 2010's wonderful Behold the Spirit and an unfinished forthcoming LP—that showcases his knack for one-man transcendentalism. His instrumentals twinkle and swell, turning four-minute expanses into short trips to an elevated plane. Less a Fahey acolyte than a broad listener with a stylized palette of his own, Tyler creates pieces that possess the warmth of great zeal, a relative rarity in the solo instrumental realm. Durham's Hiss Golden Messenger shares a sense of simultaneous eclecticism and individuality by turning funk, bluegrass, dub, country and slick singer-songwriter fare into tender, earnest ruminations on what it means to find meaning. —Grayson Currin
