The grain of Liam Gallagher's voice is a miniature history of British rock ‘n' roll—part Lennon, part Lydon, all swagger. His pugnacious post-Oasis songs, both solo and with Beady Eye, lope and strut (“The Roller”, “Flick of The Finger”), his unimpressed sneer bringing a malevolent energy to melodic rock. And while “Wall of Glass” is a bluesy huff against fakers—the Liam single that most matches his aggro reputation—the gentle, reflective swirl of “Chinatown” shows how much of his grouchy exterior is a bluff to protect his finer feelings.
