Boston Calling: New England's biggest music festival is back

• So drop the kids off at grandma's, slip on two-to-four layered tank tops or bust out your L.A. Looks Megahold hair gel (if you have any hair left) — it's time to rock.

Why it matters: Boston Calling returns this Memorial Day weekend, bringing headliners Fall Out Boy, Luke Combs and Dave Matthews Band to the Harvard Athletic Complex.

Catch up quick: The festival will be a bit different this year for the 40,000 or so expected attendees after crowd control and safety issues last year.

• There will be a new rotating main stage instead of the separate Red and Green stages that split the crowd up.
• A redesigned festival layout is meant to improve crowd flow, and more water stations will be available so aging Davers can stay hydrated.
• The indoor arena, meant to provide a cooler venue out of the sun, is returning for the first time in six years.

Zoom in: This year's lineup is heavy on older rock favorites that wouldn't be out of place sharing an iPod circa 2008.

• The exception is Friday, which features 35-year-old country star Luke Combs.
• Saturday brings emo/pop-punk nostalgia from Fall Out Boy and Avril Lavigne.

• Sunday closes with Dave Matthews Band and Vampire Weekend.

The basics: The festival is three days of music with 13 local New England artists and touring national acts you might find on a burned CD-R: Sheryl Crow, T-Pain, TLC, Cage the Elephant, The Black Crowes and Public Enemy.

• There's no on-site parking, so take the T to Harvard or hail a ride.
• Tickets are still available.
• The weather forecast calls for clouds in the 50s and 60s Friday and Saturday and sun in the mid-60s Sunday.

The local stage will feature acts like hip-hop performer Latrell James on Friday night, and alt/punk band Rebuilder on Saturday afternoon.

• Lo-fi indie artist Layzi is scheduled for Sunday evening.
