Duckworth live in Boston, northern California

Composer William Duckworth gets live performances on opposite coasts for two of his signature pieces, "Southern Harmony" and "The Time Curve Preludes."

"Southern Harmony" will be performed 8 p.m. Friday (March 16) at First Church in Cambridge, Congregational, by Boston Secession; Arvo Part, Gavin Bryars and Ruth Lomon also are featured on the program. More info here. The promotional postcard has a photograph of four women who are easy on the eyes, next to a headline announcing the name of the show, "Surprised by Beauty."

Then at 8 p.m. March 24 on the opposite coast -- Arcata, Calif., on the campus of Humboldt State University, not far from the Oregon border -- pianist Robert Elfline performs "The Time Curve Preludes." (Well, nine out of 24, according to the program.) Duckworth shares the show with Bach, Beethoven, Brahms, Janacek and Cowell.

Both Duckworth pieces are available from Emusic.
