U2 concert at Spartan Stadium will go on sale today for some of the band’s most dedicated fans.

The band’s promoter, Live­Nation, said in a statement that tickets for the general public go on sale Monday. But a sale through U2’s Web site (www.u2.com) starts today, giving fans who subscribe to the band’s site first crack at tickets for the June 30, 2010, show.

Tickets also will be on sale for one day only at the Breslin Center ticket office on Michigan State University’s campus — from 10 a.m. to 6 p.m. Monday.

The Irish rock band is stopping in East Lansing as part of its 360° Tour that started this year.

There are four price levels for the MSU show: $30, $55, $95 and $250. At least 85 percent of the tickets at Spartan Stadium will cost less than $95, with at least 10,000 tickets priced at $30.

 People who have subscribed at U2’s Web site the longest will get the earliest opportunity to buy, starting at 10 a.m. today. Those who joined the site more recently — including this week — can buy tickets Wednesday.

 Starting Monday, tickets may be bought at Livenation.com, at Ticketmaster outlets or by calling (800) 745-3000.

Spartan Stadium can seat as many as 75,000 for football games. The U2 show will be the first rock concert since the Rolling Stones played there in 1994.
