Christian pop singers Caleb and Kelsey quickly amassed a fanbase when the husband-wife duo began posting their versions of popular songs online, followed by medleys of worship songs. • Caleb Grimm also sings and plays keyboards in the Christian pop quartet Anthem Lights, which began releasing albums in 2011. • Kelsey Grimm (née Sowards) was part of the contemporary Christian pop band 1GN (formerly 1 Girl Nation) until she left in 2014 to marry Caleb. The pair met in 2012 at a Halloween party. • The first worship medley they posted online, a blend of “Oceans (Where Feet May Fall)” and “You Make Me Brave”, became a surprise streaming hit in 2017. • The duo’s 2017 album The Songs We Sang features covers of pop songs like Celine Dion’s “My Heart Will Go On” and Maroon 5’s “Maps”. Caleb and Kelsey’s 2018 LP Worship collects 10 of their worship medleys.
