<h3>Rascal Flatts, the decades top-selling and most awarded group in country music, will perform their hit &#8220;Unstoppable&#8221; on American Idol Wednesday, April 28th.</h3>
<p>This is <strong>Rascal Flatt&#8217;s</strong> 3rd appearance on Idol. They will also join Shakira on stage to perform her single &#8220;Gypsy.&#8221;</p>
<p>Rascal Flatts also just announced they will have a new single out in June and a new album out in September. With the closing of Lyric Street, it should be more than interesting to see whether they make any artistic changes with a new label.Country Music Photo Gallery</p>
