Massachusetts-based rock quartet Cave In will tease its forthcoming major label debut album with the six-song "Tides of Tomorrow" EP, due Oct. 15 via Hydra Head. None of the songs on the set, which features five originals and a cover of late great Kansas City underground rock outfit Giant's Chair's "Everest," are expected to appear on the band's forthcoming RCA album.

That set, due in early 2002, is being produced by Rich Costey (Bowery Electric, Rival Schools, Pavement). According to the band's official Web site, a handful of tracks such as "Inspire" and "Penny Racer" have been completed. Older tracks such as "Day Trader," "Sea Frost," and "Lost in the Air," the latter of which was released on a two-song EP earlier this year, are also candidates for the set.

Cave In has built a sizeable underground following on the strength of such Hydra Head albums as 1999's "Until Your Heart Stops" and 2000's "Jupiter." The band's sound has traditionally touched on everything from heavy metal to Rush-style progressive rock and textured dream pop. But the new material on "Tides of Tomorrow" moves in even more peculiar directions, particularly the uncommonly mellow, acoustic-tinged title cut.

The group will play two California shows in early August before heading to Japan for the Summer Sonic Festival. Cave In will also play the U.K.'s Reading and Leeds festivals and two additional U.K. shows afterward.
