Living up to its tradition as the premier forum for rock ’n’ roll reunions, the Coachella Valley Music and Arts Festival will host at least two of them in 2016: Guns N’ Roses — a gigantic get — and LCD Soundsystem.

The music world has been buzzing for months about a possible reunion for Guns N’ Roses, after Slash, the band’s original lead guitarist, suggested in interviews that he had finally reconciled with Axl Rose, its singer, ending a two-decade feud. After the original band fell apart in the mid-1990s, Mr. Rose maintained the Guns N’ Roses name, releasing “Chinese Democracy,” one of rock’s longest-gestating albums, in 2008 — after some 13 years of work and untold millions of dollars in production expenses — and he has toured with various new members over the years.

Now, some version of the classic Guns N’ Roses will headline the next Coachella, which will return to Indio, Calif., on April 15-17 and April 22-24, according to a person with direct knowledge of the festival’s plans, who was not authorized to discuss it publicly. The festival is expected to announce the lineup early next week.

Besides Slash and Mr. Rose, it is unclear who else will participate. Its classic lineup, which played on the band’s 1987 debut album, “Appetite for Destruction,” also included the guitarist Izzy Stradlin, the bassist Duff McKagan and the drummer Steven Adler, who was kicked out in 1990.
