Maryland’s Sweetlife Festival, which boasts both live music and high-end food vendors, is about to go into its fifth year, and it’s just announced the lineup for this year’s one-day show. Sadly, this year’s bill is less interesting than what the festival has brought in previous years. It’s overloaded with corporate radio-fodder pseudo-indie: Foster The People, Bastille, Fitz & The Tantrums, Capital Cities, St. Lucia. But there are bright spots. For one thing, it marks Lana Del Rey’s ascension to festival-headliner status, which should, if nothing else, be fascinating. For another, the undercard has a few acts well worth seeing: Chromeo, 2 Chainz, Bombay Bicycle Club, GEMS. I guess the food will be good, too. The show comes to Merriweather Post Pavilion in Columbia 5/10, and you’ll find more details here.
