Memphis’ simple approach to melody and songwriting is what makes them so great. Their melodies conjure up feelings of any easier time long past, yet vividly played out in memories and tales. Torquil Campbell’s voice has an undeniably Beatles-inflected tone, while the music lilts with Floydian melodies that make one want to sit back, relax and watch the sunset and the moon arrive. Memphis will be playing Mercury Lounge on April 14. $15. 6:30 p.m.
