Grab your hat (to you keep your head warm) and lace up them boots ( it’s colder than heck outside) because there’ll be a free country show in The Battery on Saturday.

Maryland-born brothers T.J. and John Osborne play under the name Brothers Osborne; T.J. sings and John plays guitar.

Their song “It Ain’t My Fault” was nominated for the 2017 best country duo/group performance Grammy.

The doors of Sports & Social open at 11 a.m. Saturday, and the show runs from 6:15 p.m. to 7:45 p.m.

The show was supposed to be outside but was moved in due to the recent chilly weather, which means fewer people will be able to attend, so organizers suggest showing up early.
