Recently, I had the chance to talk with two of the leading lights in contemporary indie rock. First, we visit 19-year-old phenom Lindsey Jordan of Snail Mail, whose full-length debut due next month, “Lush,” is one of the most anticipated indie releases of 2018. But when we spoke, Jordan was eager to get past the hype and talk about two of her great loves: hockey and guitar shredding. Next, we met up with Molly Rankin of the delightful fuzz-pop group Alvvays in late April at the National’s Homecoming Festival in Cincinnati. She told us about her Celtic folk past, and how studying Teenage Fanclub’s 1991 classic “Bandwagonesque” helped her become one of contemporary indie’s best writers of melancholy rock songs.
