This is what we found on Wikipedia regarding the Flatland Cavalry:

Flatland Cavalry is a country and Americana band from Lubbock, Texas. The band's original members were vocalist Cleto Cordero, drummer Jason Albers, bassist Jonathan Saenz, guitarist Reid Dillon, and violinist Laura Jane. Jane departed the band in July 2018 and was replaced by Wesley Hall.

Flatland Cavalry was formed in 2012 by Cordero and Albers, who were college roommates in Midland and performed together before moving to Lubbock, where the rest of the members came together by 2014. In May 2015, the band's debut EP, titled Come May, was released after a crowd-funding campaign was used to finance its production. On April 1, 2016, their first full-length album, Humble Folks, was released to positive reviews and comparisons to the music of the Turnpike Troubadours. Humble Folks peaked at number 17 on the Billboard Americana/Folk albums chart and number 38 on the Top Country Albums chart. The band's second studio album, Homeland Insecurity, was released on January 18, 2019.

Kaitlin Butts, who is married to Cordero and an accomplished musician in her own right, is a frequent collaborator with the band and a oft-seen part of their live shows.
