“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. “New Dog, Old Tricks” reflects what others will say has been a circuitous route to her own good fortune, but Gibson has gotten there, nonetheless, and listeners will be thankful for it.
