Sometimes it takes an infectious pop group from Sweden to alert U.S. listeners that there’s still plenty of mileage left in ‘80s-style synth-pop and guitar-pulsing new wave. And it takes a charismatic singer like Maja Ivarsson to make it fun. Ivarsson sings like a leader with no agenda other than to get people up and dancing. While the album opener, “Shake Shake Shake,” might be a literal expression of that ambition, songs like the guitar-leading “Take It the Wrong Way” and the synth dreampop of “Hurt the Ones I Love” continue the streak with melodies that flow down the ear canal. When it’s time to come across as vulnerable, she and her band bring us the reflective pillow-sobbing “Weekend,” where the synths are the only ones getting away with too much fun. Lest someone think The Sounds could actually be laid low, they return with “Great Day”: another ingenious guitar-synth blend that imagines what Blondie might have been if they'd had another decade left in them.
