Wrenclaw Blending country harmonies and slithery slide guitars, Wrenclaw captures the longing and redemption of one-horse towns and whistestop childhood memories.    Free Dirt  Pal “Young Earth” Jones: Baritone Guitar Durt Russell: Drums King Dirt: Guitar/singing   Nick Brown Nick Brown is a singer and songwriter based in Madison, Wis. A longtime musical collaborator and bass player, Brown released his debut album, “Slow Boat,” in 2012. The snow-country-tinted and heartfelt album was particularly well received among fellow malcontents and shiftless romantics.  Brown’s second album, the EP “Contender,” was recorded over three years, featuring the skilled hands and musically proficient minds of longtime Madison players and bandmates Andrew Harrison (electric and pedal steel guitars), Ben Wolf (drums, percussion, synths), Rusty Lee (keys, synths) and Pat Logterman (upright bass, gourd banjo). Scheduled for release in May 2017, the album is sonically a much larger animal, with colorful flourishes and bursts of energy surrounding songs concentrated on displaced hearts, matters of endurance and the curative power of music itself.
