At first, the bouncy acoustic guitar of the Shaky Hands’ “Summer’s Life,” coupled with lyrics about swimmin’ holes, makes you think this jangly folk-pop tune is simply about good livin’. But despite the breezy brushed drums and lackadaisical vocals, a softly squeezed accordion hints at deeper melancholy. A closer listen reveals a song about making mistakes and growing up: “I guess I’m paying for what I’ve done…I loved it then/ And I wonder what happened.” Still, the song’s constant, hammering guitar part makes for damn fine skipping music.
