Hot Steps for Cold Nights

A tango performance by the Bach Aria Soloists might seem far-fetched, but it makes perfect sense when one learns that Argentinian tango-music legend Astor Piazzolla studied Bach intensively as a young man and acknowledged him as a primary influence. In particular, Piazzolla fused the dissonant harmonies, density and complex constructions of Bach’s fugues with traditional tango forms to create the nuevo tango we’re familiar with today. Former Piazzolla collaborator Hector del Curto leads the way on the accordionlike bandoneón (tango’s distinctive instrument) for two evenings of music. Del Curto is joined by Uruguayan pianist Gustavo Casenave, BAS founder and violinist Elizabeth Suh Lane, BAS guitarist Beau Bledsoe, and guest bassist Jeff Harshbarger for Bach Aria Soloists Present: Night of Tango, tonight at All Souls Unitarian Universalist Church (4501 Walnut) and Saturday at the Lawrence Arts Center (940 New Hampshire). Both performances begin at 7:30 p.m. Tickets cost $20; see bachariasoloists.com.— Grace Suh
