In the ever-changing career of this grizzled romantic of Italian rock, there are few constants. His voice is one: a raw, warm roar, perfectly suited to pensive, synth-heavy songs of introspection or Dire Straits-style mature rock. Despite occasional sharp and angry rock-out moments, his default emotional setting tends toward the downbeat and rueful—the hoarse cry of bitter experience—although he's not averse to the sweetening effects of light reggae, a carefree acoustic strum, or even bringing in a rap verse, depending on the song's requirements.
