So, if you love Electric Six, you are one of two things: a hipster-literate cynic who sneers at stereotypical frat bros, or a stereotypical frat bro. Its message is that concertedly manly men are really just overcompensating. In contrast, “Gay Bar,” with almost 20 million hits on YouTube, greatly differs from Electric Six’s more popular songs by gleefully lambasting male sexual insecurities by blending manly vocals with nonsensically homoerotic lyrics. Songs like “Danger! High Voltage” and “Body Shot,” on one hand, glorify primal dance floor scenes of fearless sexuality. Though Heartbeats and Brainwaves features an assortment of somewhat engaging tracks, the album as a whole is riddled with poorly crafted songwriting and mutedly phallocentric motifs.
