Most bands' second albums are prone to the sophomore slump: similarly-sounding songs that lack the energy and focus of the initial release. Luckily, that's not the case with Helplessness Blues by Fleet Foxes ($10). Available for streaming online, this twelve-track opus goes beyond the band's eponymous debut with more haunting melodies, deliberate pacing, just a hint of anger, and some experimental jazz thrown in for good measure. It might not be the soundtrack to the summer, but it will go down as one of the best albums of 2011.
