Let’s develop a groove. Letting the bass bob, the drums snap their way back in line, and the guitar picks its place to drift in, all the while the vocals encompass that soulful personal funk. Now, submerge yourself in that groove allowing it to evolve and roll with the tide. Immerse yourself in the flowing tunes of Mo Lowda & The Humble opening this evening for Rusted Root at Ardmore Music Hall. This trio has a well-hone grasp of what locking in means, and while it’s easy to let that sound melodically wash over you, stay alert because that relaxed, subconscious sway has an underling power, which boils below the surface only to reveal itself when the group inevitably turns up the heat. Tonight, Mo Lowda & The Humble set the table for the percussive jam vets Rusted Root. Ardmore Music Hall, 23 E. Lancaster Ave. (Ardmore, PA), 8:30pm, $25, 21+ – Michael Colavita
