Post-hardcore rockers Saosin [ tickets ] are trying out new material on fans as they traverse the US with metalcore outfit Underoath [ tickets ].

The bands, which launched the tour last week, continue tonight (10/21) in Baltimore, and will make their way from the East Coast to the West Coast and back by late November. The Devil Wears Prada is also on the bill, and P.O.S., Person L, and The Famine appear on select dates. The itinerary is listed below.

As Saosin prepares for its sophomore album, the band is letting fans get a look at some behind-the-scenes action. Real-time audio/video feeds of the group's recent recording sessions at the Hurley clothing company's Costa Mesa, CA, studio were piped into Saosin's website, and the So-Cal rockers are now planning live feeds from their tour bus.

The band's forthcoming record, which follows its 2006 debut, is expected to hit the streets early next year. For those who can't wait, Saosin has released "The Grey" EP, which features three new songs recorded in the Hurley studio and an acoustic version of the previously released track "Come Close."

Underoath is supporting its new set, "Lost in the Sound of Separation," which surfaced last month and reached No. 8 on The Billboard 200. The Tampa, FL-based sextet is in the midst of a world tour that moves into South America in December. Underoath's full itinerary can be found at its website.
