Not only does “Are You Sure?” take the prize for being the sunniest song about winter I’ve heard all year, it also wins the best Beulah song since Beulah broke up four and half years ago. It also happens to be one of my favorite songs of the year. A Block of Yellow’s bright melodies come directly from the Elephant 6 Collective songbook and the general ’60s garage pop sound. A Block of Yellow chased with a hot cup of cocoa will run the chill right out of your fingertips and toes this winter.
