Blake Shelton can sell out stadiums, but he's certainly having fun playing for free. Tonight (March 22), the country crooner is performing an impromptu free concert for his fans in Georgia, one night after doing the same thing in South Carolina.

"Hey..... I know!!!! Maybe I should just set up somewhere and play country music FOR FREE ALL NIGHT LONG. Like we did back in the old days," he hinted in a tweet yesterday. "Brain storming... (not easy for me). If I do this it will include a s**t load of classic country music... 80's are my favorite. I'm talking one of those nights that takes days to recover from. A party. A celebration of country music. A celebration of country fans!"

The "Sure Be Cool If You Did" singer then announced he would play at the Blind Horse Saloon in Greenville, S.C., where he played more than three hours of some of his favorite tunes. "My god last night was epic," he tweeted. "Thanks again Greenville!!! I love my fans and I live for country music!!!!"

The Oklahoma native had so much fun, he is heading to the Peach State to repeat the experience. "That's it!!!! I have got to do another free country music celebration!!!" he tweeted earlier today. "Macon, Georgia.. YOU!!!! Whiskey River tonight!! Be there..."

Blake has a busy week coming up. He will return as a coach on Season 4 of "The Voice" Monday night, March 25, and will release his latest album, Based On A True Story ... one day later, on March 26. Order the album here.

"The Voice" airs Monday and Tuesday nights at 8:00 PM ET on NBC.
