Returning and slightly refining the interplay of melodic slacker rock, meandering polyrhythms, and injected noise of their 2017 debut, Lemon Lime is the Exploding in Sound debut of St. Louis' Shady Bug. Here, they anchor the songs in leader Hannah Rainey's conversational, (endearingly) rambling melodies alongside sinuous guitar counterpoint before making diversions into more complex and explosive sounds. It's a formula that effectively hooks the ear before throwing it off -- only temporarily. "Blow," for example, opens with a steady, melodic guitar line and playful, sporadically dissonant second line under vocals that weave in and out of syncopation with them. In unison with drums, brief bursts of cacophony interrupt the gentle jangle, eventually forcing the song off the rails. It picks up again with the lyrics "You blow up, it's three o'clock." Noise is used similarly, if less literally, throughout the track list, on songs that value harmonic structure as much as disruption. In the meantime, befitting the singer's matter-of-fact delivery, lyrics concern a youthful everyday, such as wearing the sweater of her missed partner, "doing doughnuts in the parking garage," and making plans to go to a show ("Afterwards we can go out and look at the moon"). Even the album's title is understated -- a reference to sharing a can of soda in "Make It Up" (another track is called "Canada Dry"). However, "Lemon Lime" also captures the record's agreeable mix of sweet and sour sounds.
