Today's recap includes summer tour announcements, special event updates and more, as compiled by TicketNews on February 26, 2009.

Def Leppard, Poison and Cheap Trick have announced plans to tour together this summer with 40 cities mapped for their run so far. They aren't the only veteran hard rock bands teaming up, though. Styx, REO Speedwagon, and 38 Special also have plans to hit the road with what they call a "Rock 'n' Roll Stimulus Package."

Australian indie rocker Missy Higgins is continuing her musical conquest of North America, and she's getting some help from two established musical acts this time around. Many of the dates on the singer-songwriter's upcoming tour leg are split between the Indigo Girls and Ben Folds. Of the 26 shows Higgins has scheduled, only two (September 27 at the University of Connecticut, and October 8 at Ohio University) are solo gigs.

After spending much of her summer traversing the East Coast and Mid-West, Higgins' new tour of the U.S. will take her from coast to coast. The trek begins September 11 in Spartanburg, SC, and wraps November 14 in Los Angeles, CA. Through September 22, Higgins will open for the Indigo Girls' tour. All dates afterwards, except for her two solo university performances, will be in support of rock pianist Folds' U.S. tour.

The Indigo Girls have celebrated their 20th year in music by embarking on an international tour, beginning in Cambridge, England on February 14, through major cities in England, Scotland and Ireland, and on to the east coast of America in mid-March. Amy Ray and Emily Saliers will bring their eclectic blend of folksy pop and modern rock back across the Atlantic to start five consecutive nights from March 14-18 at Uncasville, CT's Mohegan Sun Cabaret, then on to New York City's Town Hall for two nights.
