Scattered among Aerosmith's grimy hard rock tracks are slices of power pop, country and even psychedelia. The '70s piano ballad “Home Tonight” lifts off with high, crystalline harmonies inspired by the British Invasion, while “What Could Have Been Love” leans heavily on acoustic picking and Nashville twang and the hypnotic “Taste of India” brings back the swirling, raga-kissed grooves popular with hippie rockers.
