Jack Frusciante Has Left the Band (Italian: Jack Frusciante è uscito dal gruppo) is Enrico Brizzi's first novel. Brizzi wrote it at the age of eighteen and it was first published in 1994. The name "Jack Frusciante" is a deliberate modification of John Frusciante, the guitarist for the Red Hot Chili Peppers.
The novel, first published by independent Ancona-based Transeuropa, went out of print 15 times before the rights to it were sold to more solid publishers.
By the year 2000, the novel had sold over one million copies in Italy. A film had also been made, and the book was published throughout Europe, in the US, Japan, Korea and South America.
Brizzi is regarded as one of Italy's most poplar young writers.
Jack Frusciante Has Left the Band tells the story of the relationship between Alex, a 17 year old rebel, and Aidi, a girl who enters his life out of the blue one Sunday with a phone call. She asks about a poetry book and they end up talking about their projects and aspirations. Before they part she kisses him on the cheek. Alex falls for her, and later asks her to be his girlfriend. She begins behaving increasingly coldly to him until she states that she doesn't want any relationship because she'll be leaving for the States the following year and doesn't want to be in a long-distance relationship. Alex accepts her decision. Nonetheless, they maintain a relationship that, though not full-blown love, is stronger than mere friendship. Meanwhile, Alex takes a position in opposition to bourgeois society, rejecting the commonplace life that everyone expects him to be leading in the future ("a car, two children, a wife and a business consultant") and befriending Martino, the son of a rich family but an "outcast" like Alex himself.
