Bill and Joel Plaskett, Solidarity. This adventurous, well-produced father-and-son collaboration is loaded with lilting folk and folk/rock. The lyrics, which incorporate clever wordplay and memorable lines, range from the introspective to the political. “The Next Blue Sky” will have you up and dancing or at least tapping your foot, while the melancholic “The New California” will paint pictures in your head. The album manages to be as cohesive as it is diverse. It’s also consistently impressive.
