Chevalier Theatre welcomes back Gaelic Storm and The High Kings, a double bill of Irish music where traditional and modern sounds intersect. The multi-national Celtic juggernaut Gaelic Storm, founded in California in 1996, has a broad repertoire and well-diversified fan following: country music folks adore the storytelling, bluegrass-heads love the instrumentals, Celtic fans love the band’s devotion to tradition, and rockers simply relish the passion with which they play their instruments. The High Kings, the true heirs of Ireland’s folk heritage, have been internationally acclaimed singers of Irish folk songs since they first arrived on the scene in 2008. Tickets are $37 to $67 through the Chevalier Theatre website/Ticketmaster. To avoid online ordering fees, purchase tickets at the Chevalier Theatre Box Office, which is open on Fridays and Saturdays from noon to 6 p.m., as well as two hours before every Chevalier Theatre show.
