Celtic Connections -- The best-attended annual festival in Glasgow, and the largest of its kind in the world, Celtic Connections music festival covers Gaelic, folk, roots, alt-country, Americana, and more. It kicks off the year every January. The main venue for performances is the Royal Concert Hall, which produces the event (tel. 0141/353-8000, www.celticconnections.com).
Doors Open Days -- For a couple of weekends every September, this event arranges for the doors at buildings normally closed to the public to be opened.

Glasgow International Jazz Festival -- This annual event, usually running from the last week of June through the first days of July, brings a few top jazz acts to Glasgow.

Free events are always included in the "Fringe" schedule (tel. 0141/552-3552, www.jazzfest.co.uk).
Piping Live! -- A lone piper playing a Scottish lament in a Highland glen can bring a tear to the eye, for sure. But a band full of bagpipes blown in unison is one of the most stirring sounds on the planet. The best pipers from around the world converge on Glasgow in August of every year for the World Pipe Band Championships on Glasgow Green, the culmination of a weeklong festival with concerts across the city (30-34 McPhater St., tel. 0141/353-8000, www.pipingfestival.co.uk).
