After months of heavy industry speculation, Buffalo Springfield has announced the initial dates for its first official tour in more than 40 years. The outing will begin with a six-date run in California, where the iconic folk group had its roots in the late 1960s.

Though more dates are expected as the spring season progresses, Buffalo Springfield’s 2011 itinerary currently has stands booked June 1-2 at the Fox Theater in Oakland, June 4-5 at The Wiltern in Los Angeles, and June 7-8 at the Santa Barbara Bowl in Santa Barbara.

Buffalo Springfield will also perform as one of the top-billed acts at this year’s Bonnaroo Music & Arts Festival in Manchester, TN, taking the main stage there on June 11. The earlier California concerts, meanwhile, will feature opening support from Gillian Welch.

Onsale dates and ticket face values will vary in each of the three California tour markets, based on data from Ticketmaster.com and LiveNation.com.

Los Angeles’ onsales start April 1, with tickets priced from $89.50 up to $250. Public onsales follow on April 3 in Oakland, where tickets are set from $85 to $199.50. And while Santa Barbara’s onsales start nearly a week later on April 9, its tickets carry the lowest face values at $45 to $149 apiece.

With hits like “For What It’s Worth,” Buffalo Springfield helped launch the careers of several folk-rock icons. Its surviving original members — Neil Young, Stephen Stills and Richie Furay — will all participate in the upcoming venture.

The three musicians most recently reunited on stage in October 2010 at Young’s annual Bridge School Benefit concert, sparking speculation of larger tour plans. When they do hit the road this summer, they’ll be joined by bassist Rick Rosas (subbing for the late Bruce Palmer) and drummer Joe Vitale (filling in for the late Dewey Martin).

Until then, though, Young is touring solo with a round of spring concerts to follow the late 2010 release of his album “Le Noise.” That venture kicks off April 15 in Durham, NC, and wraps in early May.
