Abner Ramirez and Amanda Sudano of Johnnyswim lend their Christmas EP the same warmly intimate glow that made their 2014 debut album so appealing. The married duo take a classy yet homespun approach to the project’s mix of carols and secular standards (plus one original). Sudano’s smoky tones and expressive phrasing connect with both timeless hymns like “O Come All Ye Faithful” and contemporary tunes like “The Christmas Waltz.” Ramirez’s fluent acoustic guitar work and vocal harmonies add an elegant luster to each track, making one wish for a full-length holiday release from this talented twosome.
