If a city has a day of appreciation held in a musician's name, the assumption is they must be pretty good. For Patty Larkin, that is a very safe assumption. The Boston-based — and Boston-loved — singer-songwriter's warm voice, paired with her fluent guitar playing, combines to create a captivating, incredible soundscape. Her topics aren't typically cheery — see "Who Holds Your Hand When You're Alone?" — but it's always more about deep thought than it is sad.
