It’s been a long winter. Yeah, Charleston saw some snow. But the cold and cloudy skies — not to mention those heating prices — have left some feeling fed up. The remedy may be as simple as some warm rays, lively tunes, and a cold drink. The Spring Equinox Gathering at the Pour House will provide all three, burying the cold and ushering in warmer weather in style.

The gathering boasts some pretty serious bluegrass. And what better music to welcome the changing seasons? These artists bring plenty of good-natured harmonies, acoustic instruments, and verses about nature and sunny days.

On Saturday, Larry Keel will play two sets on the main stage. A bluegrass guitar virtuoso with a fierce flatpicking style, Keel is guaranteed to entertain. With Natural Bridge, his amply capable band of pickers, Keel’s music bridges the gap between traditional bluegrass and contemporary Appalachia.

The Atlanta-based duo of Jeff and Johnny Mosier work Americana stylings and folk music traditions into tasteful tunes. They’ll welcome acclaimed fiddler and mandolinist David Blackmon as well. All three are members of the ensemble Blueground Undergrass.

Sunday’s early-evening sets on the deck feature The Hawkes, a local acoustic blues, roots, and Americana combo featuring former members of Dunzip and Pour House bartender Mark Davis (on harmonica).

Due on the main stage, Birmingham-based acoustic trio Rollin’ in the Hay call their twangy music “Southern badass whiskey drinking bluegrass.” It’s got a ring to it.
