If Chvrches have a religion, it’s an unflagging devotion to infectious ’80s British synth pop—and they’ve made us believers. Every Open Eye, the Scottish trio’s follow-up to their triumphant 2013 debut, The Bones of What You Believe, is similarly dazzling, marked by the group’s signature anthemic synth-pop—grandiose, catchy-as-hell melodies kissed by frontwoman Lauren Mayberry’s soaring, crystal-clear vocals. The Glasgow outfit played a killer set at fall’s Boston Calling the last time that they were in town; this time around they’re headlining back-to-back shows at the House of Blues on June 3 and 4. 

Chvrches play the House of Blues at 8 pm on June 3 and 7 pm on June 4 at the House of Blues, 15 Lansdowne St., Boston; $27.50-$45; livenation.com
