Leeds four-piece Mush continue to direct their loose, angular, post-punk-injected grievances at the unsavory sociopolitical landscape on their second album, Lines Redacted. Following their full-length debut, 2020's 3D Routine, by a year, it returns that album's Lee Childs to the producer's chair as well as matching its relatively generous 12 tracks. What's a little different this time is the relentless churn of similar riffs and meandering, duo-guitar connective tissue that makes Lines Redacted a tenser, more-frustrated (and frustrating) experience. The album opens with "Drink the Bleach," a midtempo song whose chorus repeats its unison guitar and one-note-at-a-time keyboard line alongside the words "so drink the bleach" in choruses -- delivered by the idiosyncratic, Fred Schneider-reminiscent Dan Hyndman -- that only slightly distinguish themselves from the verses. Many of the songs follow this formula, though the band do change up the pace on entries including the punkier, urgent "B2BCDA," the lively "Blunt Instrument," which offers a much-distorted chorus, and, midway through, an atypically relaxed groove materializes on "Seven Trumpets." Elsewhere, "Morf" is a distortion-filled instrumental, while the jauntier "Bots!" offers contrastingly low, grungy guitar tones and sauntering rhythms. The set closes with "Lines Discontinued," which leaves listeners on an over-seven-minute, shape-shifting rumination full of meandering arpeggios befitting an album that ultimately straddles catharsis and tedium. While the individual songs may not be as fun on average as those of its predecessor, Lines Redacted does drive home the feeling of dissatisfaction while, like a Ramones under the influence, locking into an admirably irreverent, distinctive persona.
