The New Orleans rockers gave Chicagoans a taste of their alternative, southern rock Saturday night at Concord Music Hall.  Unseasonably warm, the guys of The Revivalists probably felt right at home, especially after being received so fervently by fans.  The seven musicians that make up the band artfully played hits from each of their studio albums to give concert goers a sampling of all of their work.  Their smooth fusion of rock and soul made for a great night of music.
