Country and rock-and-roll have had a fairly close relationship, really since the genres early days. There's been a few country-southern rock style acts that have hit big at country radio and one of them was in 2015.

A Thousand Horses is a band that started about a decade ago and they draw influences from southern-rock bands like Lynyrd Skynyrd and the Allman Brothers. A Thousand Horses got their name off one of their songs on their first EP.

In 2014, A Thousand Horses signed with Big Machine Label Group and would later release their only big hit, "Smoke."

Released in January of 2015, "Smoke" would climb all the way to #1 on the Mediabase and Billboard country airplay charts by June of that year.

Written by lead-vocalist Michael Hobby, Ross Copperman and Jon Nite, the song was the first single off their album, Southernality.

A Thousand Horses would only chart three more singles, with the highest being "This Ain't No (Drunk Dial)" (#22) in January of 2016. The other two failed to crack the top 40.

"Smoke" has a certainly quality about its melody and music that pulls you in. It was one of the biggest hits on country radio in 2015 and maybe they can make a comeback one day.
