Rascal Flatts celebrated a very special anniversary this past week. The CMA Vocal Group of the Year nominees spent the afternoon at Monroe Carell Jr. Children's Hospital at Vanderbilt in Nashville, where they visited with patients and performed.

The superstar vocal trio first partnered with the hospital 10 years ago, and in the years since then they have raised $4 million for the facility, which provides comprehensive medical services for children. The Rascal Flatts Pediatric Surgery Center was named after the trio in recognition of their long-term support.

The group also held their annual fundraiser for the children's hospital at the Country Music Hall of Fame in Music City on Thursday night (Oct. 29), featuring special guests RaeLynn, Scotty McCreery and Henry Cho.

Rascal Flatts recently released a new single, "I Like the Sound of That," from their ninth studio album, Rewind. That album debuted at No. 1 on Billboard's Country Albums chart, making the trio one of just four acts to have eight consecutive albums debut in the top spot during the SoundScan era. They are also the top-selling country vocal group of the past decade, having scored 15 No. 1 songs, sold over 22.8 million albums and over 29 million digital downloads worldwide. Their recently-wrapped Riot Tour kept the success rolling on the live side of their career, too, where they have sold nine million concert tickets to date, making Rascal Flatts one of the top live attractions across all genres.
