Gladden appeared at the 2011 KISS Expo in Indianapolis, IN, signing autographs alongside KISS drummer Eric Singer and performing “Black Diamond” with KISS tribute band Mr. Speed. He has made several guest appearances with other bands. In 2009, Barney and Friends aired several episodes featuring Robot Gladden (then age 5) as a rock and jazz drummer – the episodes remain in rotation worldwide. At age seven, he became one of the youngest artists ever endorsed by Pearl Drums and one of the youngest radio personalities ever to host his own show, “Robot’s Rock Block.” Also at age seven, Robot Gladden was a featured artist in the Chuck E. Cheese in-store video entertainment series, which aired hourly in Chuck E. Cheese restaurants nationwide during the spring of 2011.

Gladden began his music career as an internet sensation. He and several other young musicians formed a junior all-star band, at a school in Southlake, Texas, called For Those About to Rock School. The young group opened for Rick Springfield and Spin Doctors at Liberty Fest near Dallas in May 2011.

In 2012, the group began to search for a new lead singer and a lead guitarist. They added 11-year-old Angelina Baez from Los Angeles, California as lead vocalist and 12-year-old Yuto Miyazawa from Tokyo, Japan. Yuto had already appeared twice on The Ellen Show and had toured with Ozzy Osbourne as lead guitarist. The group, now renamed, The Robotix, released a five-song EP co-written and produced by drummer Aaron Sterling called Rock ‘n Roll on December 4, 2012 via iTunes. The EP includes three original tracks and two classic rock covers. Members of The Robotix have been featured on The Ellen Show, Good Morning Texas, Conan O’Brien’s television show, Barney and Friends, and in Chuck E. Cheese restaurants. The band was named as a Top 60 Finalist on America’s Got Talent (Season 8).
