Brad M. Carlson (Stagename: Bun E. Carlos), is the original drummer for American rock band Cheap Trick.

Carlos has two side bands with former Cheap Trick bassist Jon Brant: The Bun E. Carlos Experience, and the Monday Night Band.

Carlos is left-handed, but has alternated between left and right-handed playing throughout his career. He has several writing credits, the most notable of which is the drum solo track "Who D'King", from the album All Shook Up, and Bun E. in a Box (2004), a drum sample CD.

In 2009, Carlos formed a new band, Tinted Windows. This new project ran alongside each of the artists' main bands. Tinted Windows played its first publicized gig at SXSW in Austin, Texas on March 20, 2009, and appeared on late-night network TV shows. Their album was released on April 21, 2009.

On March 19, 2010, Cheap Trick issued a statement that Carlos had stopped touring Cheap Trick but that he still remained a band member. Cheap Trick guitarist Rick Nielsen's son Daxx was named in the statement as the touring drummer.

In 2011, Carlos once again debuted a band at SXSW in the form of his new project Candy Golde.

In 2013, Carlos filed a lawsuit against his former Cheap Trick bandmates - on February 26, 2015, Cheap Trick announced that the lawsuit was over.

On August 21, 2014, he filled in for drummer John Cowsill on a sold out Beach Boys concert in Princeton, Illinois.
