NEW YORK – Fleetwood Mac is heading back on the road, and that means the top-selling group will release new music – sort of.

On its 34-city North American tour, which kicks off April 4 in Columbus, Ohio, the band will perform two new songs, and it could mean a new album will follow. Or not.

Stevie Nicks recently sang on tracks that Lindsey Buckingham, Mick Fleetwood and John McVie worked on, calling the sessions “great.” But Nicks also says she’s not sure where the band fits in today’s music industry.

“Whether or not we’re gonna do any more (songs), we don’t know because we’re so completely bummed out with the state of the music industry and the fact that nobody even wants a full record,” she said. “Everybody wants two songs, so we’re going to give them two songs.”

Nicks said depending on the response to the new tracks – which Buckingham calls “the most Fleetwood Mac-y stuff ... in a long time” – more material could come next.

“Maybe we’ll get an EP out of it or something,” Buckingham said.

Nicks will continue to record solo albums, though. The group is celebrating the 35th anniversary of the best-selling “Rumours” album, which has moved some 20 million units in the United States. She knows that’s not possible again, despite the success of Adele’s “21,” which has sold 10 million units in America in less than two years.

“This is Adele’s ‘Rumours,’ ” Nicks said. “She had a baby, she’s going to take a year off to take care of her baby – that’s why I never had any kids. She’s going to go back and start writing again, you never know what the next record’s going to be. Is it going to sell 10 million records? You don’t know,” she said.

Buckingham said he initially wanted to record a new album, but Nicks “wasn’t too into that.” But the guitarist and singer knows that new music isn’t a priority for the band’s fans.

“It wouldn’t matter if they didn’t hear anything new. In a way there’s a freedom to that – it becomes not what you got, but what you do with what you got. Part of the challenge of this tour is figuring out a presentation that has some twists and turns to it without having a full album,” he said.

Fleetwood Mac, which was formed in 1967, last released an album in 2003, though they hit the road in 2009. Nicks and Buckingham – who joined the band in 1974 as a couple – both released solo albums and toured last year. Buckingham had suggested that Fleetwood Mac tour last year, but says getting everyone to agree was tough.

“If you look at Fleetwood Mac as a group, you can make the case of saying we’re a bunch of individuals who don’t necessarily belong in the same group together, but it’s the synergy of that that makes us so good. But it also makes the politics a little more tenuous,” he said. “You can say that not only can it be a political minefield, someone’s always causing trouble, right? I caused trouble for years so I can’t point any fingers.”
