Only a few weeks ago, Detroit duo Dale Earnhardt Jr. Jr. released their debut full length album It's A Corporate World. The album has received massive praise, and deservedly so. Today, a fan made video for the band's track "Simple Girl" was put up on YouTube, which perfectly fits the charming, summery sound of the song and the band. The girl featured in the video is even a huge fan of the band, having attended their recent Los Angeles show. The duo are also set to perform in two days in their hometown of Detroit, as well as at this years Lollopalooza and Austin City Limits festivals. You can watch the unofficial video for "Simple Girl" above.
