Roberta Flack and Donny Hathaway tribute: They were the kind of duet partners who brought something out of one another that wasn’t revealed in their solo performances. Gwen Mathews and Robert Robinson, both among the Twin Cities’ finest singers, are similarly simpatico as they interpret “Where Is the Love,” “You’ve Got a Friend” and other favorites from the Flack/Hathaway songbook of ’70s soul.

Thomasina Petrus Sings Lady Day: The Twin Cities singer-actress was masterful as Billie Holiday in “Lady Day at Emerson’s Bar and Grill” at the Jungle Theatre last year. When she brings the Holiday repertoire to a nightclub, Petrus educates with back stories and illuminates with songs, giving the evening more depth and dignity than the wonderful theater vehicle.

Tommy Emmanuel and John Knowles: The late and greatly admired Chet Atkins created a small, exclusive club called “Certified Guitar Player” for finger-style guitarists he admired. Two of the three living CGPs — Aussie Emmanuel and Texan Knowles, who earned a Ph.D. in physics — have teamed up for an album, “Heart Songs,” and a duo tour. The record offers intriguing instrumental interpretations of such emotional classics as “How Deep Is Your Love,” “I Can’t Stop Loving You,” and “I Can’t Make You Love Me.” Considering Emmanuel has often played Ames Center in Burnsville, this intimate engagement is that much more exclusive.
