Key Grip - “It’s Gotta Swing”. Key Grip sets a high bar for blues wherever we play. We explore many shades of blues, up tempo and slower tunes, tunes with tasty, interesting progressions, great lyrics and well, tunes that just need a bit of work to get right. We draw on a range of influences from blue stalwarts like Percy Mayfield and B. B. King through to the soul, gospel and blues of Ray Charles, Aretha Franklin and Earl King.
