Deep into the Luxembourg Signal’s self-titled album is the song “We Go On,” a dreamy four minutes of popgazing that evokes the sweet melancholy of Sarah Records bands and all the contemporary indie-poppers who have followed. There’s a literal truth to “We Go On” too — the Luxembourg Signal is comprised of members who were involved in the movement the first time around. The band features Johnny Joyner, Beth Arzy and Brian Espinosa, all of whom played in Aberdeen, along with Betsy Moyer and Ginny Pitchford. The album was made at producer David Newton’s Rollercoaster studio in Burbank, with cameos by Aberdeen’s John Girgus and the Melvins’ Dale Crover. Alternately jangling and noisy, hopeful and grounded, spacey and focused, sunny and cloudy, the album embraces the conscious sentimentality of the best indie-pop: In other words, you hear pretty, but you think bittersweet. “The Luxembourg Signal” is out this week on Shelflife Records, with a limited run of electric blue vinyl.
