It’s not surprising that Taylor Momsen channels a lot of energy on her rock-and-roll-heroine-in-the-making debut album with her band The Pretty Reckless. The songs, all written by Momsen and Ben Phillips with their producer Kato Khandwala, run the gamut of emotions, alternating at times between seething rage and a bruised vulnerability. With Momsen’s inky vocals, pummeling riffs, and swaggering attitude, it sounds a bit like what might have happened had Led Zeppelin been fronted by “a chick.” The album’s ferocity could raise an eyebrow from those expecting a pretty, blonde teenager to gravitate toward straight-up pop songwriting. “It’s heavier than people might expect from me,” says Momsen, who is best known as the actress who plays Jenny Humphrey on The CW’s Gossip Girl. “But this album is the most honest expression of who I truly am.” It is an unflinchingly honest chronicle of Momsen’s experiences, filtered through her unique point of view. “The record is about life,” she says. “It covers everything: love, death, and music itself. It’s rock and roll. It’s sex. It’s drugs. It’s religion. It’s politics.”
