NEW YORK — iTunes is putting its stamp on South by Southwest, piggybacking on the annual event with its own music festival.
The company said Wednesday it will debut its popular iTunes Festival, a free concert series held in London for the past seven years. While the London version is a 30-day event, the U.S. festival will feature five nights of rock, country, pop and hip-hop at South by Southwest, an international showcase for music, film and interactive projects to be held next month in Austin.
