BREMERTON — Bremerton-based alternative rock band LTTRS will celebrate the release of their second full-length album, “Worlds We Roam,” with a special hometown CD-release gig at The Manette Saloon on Friday, April 22.

LTTRS will perform “Worlds We Roam” in its entirety, with Dream Big, Cityscapes, and The Learning Process opening the show. Tickets $5 at lttrs.brownpapertickets.com.

For Worlds We Roam, the band provide an expansive and entrancing musical backdrop to 12 songs following the exploits of a bevy of classic DC Comics characters. The music ignites this conceptual thread on tracks like the first single, “Frances,” featuring Jesse Lawson [ex-Sleeping with Sirens].

“Since this is a concept album, and the songs are about DC characters, ‘Frances,’ in particular, is about Harley Quinn’s obsession with the Joker,” said LTTRS frontman Zander Grey.

The concept album also features “Man of Tomorrow,” about Vandal Savage, “Hey! Mr. Wilson,” about Deathstroke, “Legacy,” featuring Mike Herrera of MxPx, a song about Batman and his son, Damian, “Elapsed Ascend and Elapsed Descend,” about the speed force, related closely to the Flash, “Magic Confidence Man,” about Doctor Fate and John Constantine, “My Own Nebula,” about the Green Lantern Corps, “Sensus Communis,” about Lex Luthor, “The Hooded Enigma,” about Red Hood, and “Frances Quinn,” the acoustic version of “Frances.”
