For this classical music lover, this is one of the most enjoyable events of the year. While visiting Lowertown galleries during the St. Paul Art Crawl on Saturday, feast your ears on six hours of 15-minute mini-concerts at six venues in two buildings next to the St. Paul Farmers Market: The Northwestern Building (275 E. Fourth St.) and the Northern Warehouse Building (308 Prince St.). You have 15 minutes to walk between them and get your fill of music, performed by some of the best players and ensembles in town. It’s set up in two-hour blocks at each venue, meaning the musicians will repeat the same program four times, starting on the hour and half-hour.

If you like it old: The Baroque Room in the Northwestern Building will host Flying Forms playing music of J.S. Bach (1-3 p.m.) and the Bach Society of Minnesota playing Bach, George Frideric Handel and others (5-7 p.m.). Upstairs in Suite 782, you’ll find Ladyslipper playing 17th-century lute and viol music (1-3 p.m.), while the Northern Warehouse’s AZ Gallery will host outstanding lutenist Phillip Rukavina (1-3 p.m.) and cellist Tulio Rondon playing a Bach Cello Suite (3-5 p.m.).

If you like it new: The dean of local new music ensembles, Zeitgeist, will perform newly commissioned works at its Studio Z in the Northwestern Building (1-3 p.m.) and host two composers from American Composers Forum premiering new pieces, DeVon Gray and Joe Horton (5-7 p.m.). Up in Suite 782, RenegadeEnsemble will play pieces by Jordan Noble and Katerina Gimon (5-7 p.m.).

If you like opera and musical theater: Hang out at Nautilus Music-Theater’s space in the Northern Warehouse, where there will be performances by artists from Skylark Opera Theatre (1-3 p.m.), Nautilus (3-5 p.m.) and Minnesota Opera (5-7 p.m.).

If you like chamber music: The 3-5 p.m. slot is your time to crawl. There’s baroque duo Cerulean Fire (the Baroque Room), the Pavia Wind Quintet (Studio Z), a student ensemble from the Chamber Music Society of Minnesota (Suite 782), and the Mill City String Quartet (the Black Dog Café in the Northern Warehouse). The Black Dog will also have a string quartet of musicians from the Minnesota Sinfonia (1-3 p.m.).
