D2B (Thai: ดีทูบี) was a Thai boy band from the Thai record label, RS promotion. The name "D2B" was created from the first letters of the members' nicknames, Dan, Big, and Beam, in which one name started with a "D" and 2 names started with a "B". "D2B" was one of the hottest boy bands in Thailand[citation needed]. However, on July 22, 2003, Big was in a major accident where his car flipped into a dirty roadside canal, leading to a bacterial infection in his brain. After being in a coma and persistent vegetative state for 4 years, he died on December 9, 2007.

After Big had slipped into a coma, Dan and Beam continued their musical careers and released several duo albums. They went by the name "Dan-Beam."In 2005 Dan and Beam came out with their first album together called "Dan-Beam the album". Then in 2006 they came out with the second album " Dan-Beam the 2nd album Relax" and in 2007 they came out with their last album together "Dan-Beam the 3rd album Freedom". After Panrawat Kittikorncharoen (Big) died, Worawech Danuwong (Dan) was then sold off from RS entertainment, leaving Kawee Tanjararak (Beam) in RS.
