With its fifth album, The Edge of Silence, Solas has transformed itself from a forward-looking Irish folk band into a full-fledged pop group with Celtic tinges. Bandleader Seamus Egan, co-writer of Sarah McLachlan’s smash “I Will Remember You,” also wrote the score for Dancing on Dangerous Ground, partially composing it with drum loops. Egan’s electronics experience has carried over onto The Edge of Silence, and some songs, such as the electro-percussion-driven “Darkness, Darkness,” sound more like Afro Celt Sound System than Solas. There are enough roots touches on the record to keep traditional Irish-music fans happy, but the multitalented Egan isn’t one to keep still for their sake. So catch the vaguely Irish Egan & Co. while you still can. They play with Antje at 8 p.m. at the Barns of Wolf Trap, 1635 Trap Road, Vienna. $17. (703) 218-6500. (Christopher Porter)
