Concord first pitched the idea of Reinhart doing a covers album. Reinhart agreed since her deepest memories are of classic rock songs in the repertoire of her parents' 1960s cover band, Midnight. The result, What's That Sound, features most of her favorite classic-rock and pop songs, all of which were originally released between the years of 1967 and 1969.^[10]

What's That Sound? was recorded to tape at Sunset Sound Recorders using analog recording and vintage instruments, to achieve a sound "true to the era."^[11] Each song on the album was recorded live in the studio as a band, and most of the raw takes were kept for finalized tracks.^[11] The album was produced by Concord President John Burk and co-produced by Reinhart.^[3] Bill Schnee mixed the album, Reinhart's father, Harry, provided guitar, Reinhart's mother, Patti, sang backup vocals, Scott Bradlee played piano for three tracks, while Casey Abrams was featured vocalist on two tracks and instrumentalist on several others.^[11] With the album, Reinhart wanted to draw connections between the 1960s and the present day, describing both as "turbulent, yet hopeful times," and she also wanted to spread the idea of "people coming together through love and music" and hopes that the album will help listeners "become more aware and more in tune with each other."^[11]

What's That Sound? debuted at 67 on Billboard's Top Album Sales chart, for the week dated October 14, 2017.^[9]
