For nearly a month, Beck's summer Sea Change tour has brimmed with the spirit of the heartfelt confessionals off his latest album. After Saturday's show at Red Rocks, however, the tide has ebbed somewhat.

While still heartfelt, the once-three-band bill is a third less confessional after opener Dashboard Confessional has left the tour following the stop in Morrison, Colorado, outside Denver, according to an Interscope Records spokesperson. The band cited "circumstances beyond our control" as the reason for its withdrawal in a post on its Web site Saturday.

Regretful for the exit, which must come as a severe disappointment to any member of Dashboard's dedicated fanbase holding tickets to the remaining eight shows, the group also had nothing but praise for the headliner.

"We STRONGLY recommend that you do yourself a favor and take in the rest of their tour dates and experience the creative brilliance that is Beck," the post reads. "We have had a great time on this tour; we were treated so well by Beck and his crew that we will be forever grateful. Again we are sorry."

For those who don't abide by Dashboard frontman Chris Carrabba's suggestion, they can receive a refund at the point of purchase.

The band vowed to return to the road in August, on a headlining tour with MxPx, Rooney, Brand New and Moneen -- as well as a new album -- in tow. A Mark, A Mission, A Brand, A Scar is due August 12.

Before their departure, Dashboard, Beck and the other tour opener, the Black Keys, had played 15 shows together. The Sea Change tour continues through June 27 in Irvine, California, in which time the garage blues duo will extend their set to fill the void.

Two shows this week have been downsized to smaller venues, with Wednesday's show in Vancouver shifting from the Plaza of Nations to the Orpheum Theatre, and Thursday's gig in Portland, Oregon, moved from the Rose Garden Arena to Keller Auditorium.
