This summer will see a new prog-rock partnership when Yes and Peter Frampton hit the pavement for a co-headlining tour of the United States.

The veteran performers had previously announced just a handful of dates for the trek, including a July 2 performance on the classic rock stage at Summerfest in Milwaukee, WI. But with a dozen recent additions to the calendar, they’ll now be on the road from June 8 at Kravis Center in West Palm Beach, FL, through July 15 at Snoqualmie Casino in Snoqualmie, WA.

The five-week routing includes engagements on June 15 at Tower Theatre in Upper Darby, PA; June 26 at Nikon at Jones Beach theater in Wantagh, NY; and July 11 at The Mountain Winery in Saratoga, CA. Yes and Frampton are expected to announced a few more dates to round out their run to 25 cities.

Tickets are already on sale for select tour stops, and some shows are still awaiting onsale dates and times. However, a number of concert markets have public onsales coming up over the April 9-10 weekend. More details are available on Yes’ official Web site.

Both the veteran band and rocker are co-headliners on the billing, though Yes’ site lists them as the closing act for all but one night of the tour, a free July 4 show at Lake Forest Venue in Blue Ash, OH.

In fall 2008, Yes ignited controversy when it announced plans to tour with a replacement for singer Jon Anderson, who was temporarily barred from touring due to health concerns. Tribute band singer Benoit David was confirmed as the stand-in, and will continue to provide vocals for his veteran companions on the upcoming summer 2010 tour.

Most recently, Yes co-headlined a summer 2009 tour with Asia, with guitarist Steve Howe splitting his stage time with both prog-rock bands.

According to Frampton’s official Web site, the summer concerts will run over three hours each night. While both acts will focus on their classic hits, Frampton will also be supporting his upcoming “Thank You Mr. Churchill,” due April 27. Yes’ most recent studio album was the 2001 effort “Magnification,” though the band has released several live and compilation discs since then.
