To say Luke Bryan is killin' it is an understatement. The dude could earn a rare pair of No. 1 albums this year.

In March, the Nashville-bred singer earned his first Billboard 200 No. 1 album with Spring Break...Here to Party, a compilation record of four EPs released every March since 2009. Tomorrow, he releases Crash My Party, his fourth full-length studio effort. Given the performance of the lead single title track—a Top 20 Billboard Hot 100 single and a No. 1 Country Airplay hit—Bryan is certainly in the running to produce two chart-topping albums in one year.

The hard-working countryman is only one of many male country singers currently having their moment outside traditional country music and into more mainstream circles. From country vets like Tim McGraw and Kenny Chesney to newcomers like Tyler Farr and Hunter Hayes, here are 20 acts shaking up the iTunes and country radio charts.
