There's no doubt that Aerosmith's bad-boy swagger sprouted from the demonic riffs and slithering boogie that powered Stones tracks like “Jumpin' Jack Flash.” But Aerosmith also have a knotted syncopation—a product of studying the spiky funk jams of Sly & The Family Stone's “Thank You (Falettinme Be Mice Elf Agin)”—while Steven Tyler's androgynous screech perfectly blends Robert Plant's banshee wail and Janis Joplin's bluesy rasp.
