The Grove Park Inn has ramped up its concert series in celebration of the inn's centennial. February's Celtic Adventure Weekend brings an especially explosive music event: Solas in concert. The Irish-American group formed in New York in '94. Its past and present members (including Seamus Egan, Karan Casey and Asheville-based John Doyle) have gone on to achieve luminary status in Celtic music. Solas's new album, Shamrock City (out Feb. 5) contains themes of "immigration, mining, murder and the remarkable history of Butte, Mont." Concert at 8 p.m. on Friday, Feb. 1. $39. (Gaelic Storm performs at 8 p.m. on Saturday, Feb. 2. $49.) http://www.groveparkinn.com.
