A successful country songwriter whose tunes have been recorded by Ricky Skaggs, George Strait and Darryl Worley, Steve Leslie is a Kentucky native who came to Nashville in 1992. With a background in jazz, Leslie has written a musical play titled Umbrella, which explores the effects of memory on human relationships and the eternal search for the romantic ideal. Leslie is an accomplished guitarist who has taught songwriting and jazz history, and it’s this grounding in harmonically sophisticated composition that he says informs Umbrella. Scored by pianist Danny Mitchell, tonight’s show is being presented as part of the Metro Parks Theater Department’s ongoing New Play Reading Series, with Leslie and other performers featured. The great country-music play has yet to be written, but Leslie is an ambitious songwriter — any Nashville tunesmith who aspires to write a musical in the mode of such giants as George Gershwin or Stephen Sondheim deserves a listen.
