Roberto Vecchioni

It reached absolute peaks in the second half of the '70s, albums like "Ipertensione," "Elisir," "Samarcanda," or "Calabuig" are true masterpieces. After "Il Grande Sogno" in 1984, it started to wobble a bit with some albums that were somewhat lackluster (and I don't give it 5 stars just for these), only to make a nearly complete comeback in the early '90s.
