Truly on a creative roll, the David Crowder Band follows up its award-winning Church Music album with a short but potent EP offering, Summer Happiness. Fans mostly familiar with Crowder’s explosive full-band sound may be surprised by the stripped-down renditions of four Church Music tunes included here. Crowder’s earnest, slightly rough-edged vocals and propulsive acoustic guitar work transform these songs into campfire-style folk hymns. “Alleluia, Sing” and “How He Loves” lose none of their Spirit-filled fervor in these simplified renditions — if anything, the humble yearning for salvation they express has a deeper resonance. “Oh Happiness” retains some of its expansive scope thanks to its sing-along chorus, while “Shadows” has its message of resolute faith underscored by a simmering backbeat. Crowder and his group have already redefined praise music thanks to their freewheeling mix of rock, folk and dance music elements and kinetic sense of showmanship. Summer Happiness turns down the volume of the DCB’s ecstatic worship experience without losing its essential artistry or passion.
