Calla is a New York City-by-way-of-Texas trio that specializes in dark, cinematic soundscapes. In truth, though, they gradually seem to be shifting toward more traditional songwriting - verse/chorus/verse, etc. But, thankfully, their dark edges remain evident and decadent, so I don't think there's much danger of these guys ever going full-on, shiny-happy "pop."
As for what they sound like... hell, I don't know. Perhaps a bit like Starflyer 59 with their more recent stuff; perhaps a bit like Calexico with their earlier material. But that doesn't tell the whole story, so please feel free to listen for yourself.
Their new LP, Collisions, will be released in the U.S. on September 27th.
