Caleb and Kelsey

Caleb + Kelsey are an American husband-and-wife duo who built their following on YouTube by releasing harmony-driven covers and medleys of pop, country, and worship songs. Caleb Grimm came from the Christian pop group Anthem Lights before joining with his wife Kelsey to record acoustic and piano-based arrangements that combine two well-blended voices with stripped-down instrumentation, a style that translates equally well across secular and worship repertoire.

Their breakthrough came through medleys pairing contemporary worship songs, such as their combination of Hillsong United's «Oceans (Where Feet May Fail)» with Bethel Music's «You Make Me Brave», which spread widely online and established their format of blending two related songs into a single continuous arrangement. That approach became their signature, applied to secular movie themes and country duets alongside worship staples like «10,000 Reasons» and «What a Beautiful Name».

The duo has released studio albums built from this catalogue, including a set of secular covers and a worship-focused collection that reached the Billboard 200 and the top of the Christian and independent album charts. Their appeal rests on accessible, radio-friendly vocal arranging rather than original songwriting, positioning them as interpreters who bring pop, country, and worship songs together for a broad, faith-adjacent audience.
