“New Dog, Old Tricks” recaptures and reinvents two songs co-written with ex-bandmate Scott Melott. Look for a hauntingly desperate but utterly timely delivery of “Miles City,” a song so cloaked in despair that it clings to the listener long past the last note. The frustrated communicator comes out in “Walls Come Down,” a moody piece with a pop/rock edge.Both songs represent the versatility of Gibson’s songwriting prowess and underscore the “huge emotional growth” she’s undergone since the Groobees disbanded.
