Truthfully, I love nothing more than unexpected collaborations. Paul McCartney and Michael Jackson. Jack White and Loretta Lynn. Kanye West and Justin Vernon. Whether or not you’re a fan of one or all parts, these musical oddities typically bear bad ass fruit. And now, the same goes for Gallo & Hull – at least, that’s what we can only expect from their special gig tonight at Johnny Brenda’s. The pair – that is Toy Soldier’s Ron Gallo and Nashville-based singer-songwriter Jordan Hull – met years ago after a clash with some strange folks during an early dawn in Memphis, causing Gallo and his crew to seek refuge in Hull’s Nashville home. It was there they connected over a mutual admiration for blues, soul, and vintage rock ‘n’ roll (plus, of course, their respective sonic creations), fostering the framework for a beautiful friendship that spanned numerous tours through the years. And, last fall, they took that up a notch when they started work on their Midweek Mountain Getaway split in Philadelphia, where Hull set up camp on Gallo’s couch for a few weeks. Supported by Boston’s Boy Without God and local pop-rock outfit the Fleeting Ends, Gallo & Hull should prove to be one hell of a collaboration. Johnny Brenda’s, 1201 N.
