When dreamy post-rock trio Old Worlds released their "Such a Willful Creature" EP last May, they intended to give fans a little more than an ephemeral glimpse of greater things in store.

A little more than a year later, their first full-length LP, "A Light in the Corner," is ready to shine. Building on the tracks from the Willful Creature EP, "A Light in the Corner" is ten tracks of melodic, experimental indie rock beauty.

"The songs on the new album began as an emergence from a very dark place," said frontman Aaron Sturgill. "I had let myself slip into some pretty destructive habits and relationships. Writing about pain and loss was cathartic, and I convinced myself other people should hear it, too."

The album is a heady, orchestral, otherworldly mix of shimmering guitars, strings, synth and percussion. Sturgill has always been moved to create music with enough depth and complexity to hold its own without relying heavily on vocals. In fact, only half of the tracks on "A Light in the Corner" include singing.

"We consider the voice to be one instrument among many," Sturgill said. "With instrumental music, each instrument is given the opportunity to take the lead."

That philosophy seems fitting coming from a musician who started out as a one-man band in his basement with some loop pedals, a few guitars and a drum set. The lineup has now expanded to include Mike Poston on drums and Adam Langdon on bass.

For their album pre-release show at Carabar on Friday, the trio will be joined by a keyboard player, a string trio and guest vocalists. Advance copies of "A Light in the Corner" will be available to fans that night, with a wider release planned for July 23. Nick Tolford & Company and The Washington Beach Bums open the show.

And how would Sturgill describe an Old Worlds live show to the uninitiated?

"It's a meditative atmosphere that gets loud sometimes."
