The centerpiece for any Billy Squier collection has to be 1981’s “The Stroke,” a monster of a song that features a boot-crunching beat, pummeling power chords, and vocals both wailed and chanted. There’s plenty more where that came from: Check out the finger-snapping rhythm and slippery ’80s synths of “Rock Me Tonite,” or the funky stuttered bassline that drives “Emotions in Motion,” punctuated with shards of squealing guitar and Squier putting on the hottest howling jag this side of Robert Plant.
