There have been a lot of conversations about rock music’s current cultural import recently, but the New York indie four-piece LVL UP aren’t trying to be saviors. They humbly keep alive the fuzzy ’90s sounds of bands like Neutral Milk Hotel, Guided by Voices, and Sebadoh. Fortunately, their jump from smaller labels to indie-rock mainstay Sub Pop for their third album, last year’s Return to Love, didn’t change their sound in any drastic way: This band should be allowed to do its thing, because “its thing” is unique. Three of the band members contribute songwriting, and their lo-fi aesthetic is not to be confused with a lack of ambition or lazy musicianship — for one thing, Mike Caridi and Dave Benton’s guitar work tends to be bold and blazing. Overall, they’ve proven themselves worthy of their spot on the Sub Pop roster. The future of indie rock is hard to forecast, but it’s easy to imagine LVL UP being at its forefront for years to come. Set to open Monday’s show are Palm and Double Grave.
