If it’s true that country music is...

If it’s true that country music is more popular than ever, thanks in part to a new wave of female vocalists, then Sunday’s concert at Library Park in El Segundo should be standing-room-only. The reason: The

featured band is “The Mustangs,” a four-piece call-female group that puts on an upbeat, progressive country show.

The concert is the second this year in a summer-long program sponsored by the El Segundo Recreation and Parks Department. The series, which runs through August, will also present classical, Dixieland, salsa and jazz productions.

The Mustangs have toured the Western United States, Scandinavia and Europe. Locally, they have played the stages of the L.A. County Festival, the Gene Autry Museum and the Palomino Club in North Hollywood.

What: Concert in park, featuring country music.

When: Sunday 2 to 4 p.m.

Where: Library Park in El Segundo, Main Street and Mariposa Avenue.

Cost: free.

Background: This is part of the city of El Segundo’s summer concert-in-the-park series. Upcoming concerts will feature the Tom Talbert Jazz Orchestra, the Southbay Coastliners (barbershop quartet and chorus), the Palos Verdes Symphonic Band and the Susie Hansen Band (Latin jazz and salsa).
