Michael Allen Muir is an American singer who is the lead vocalist and the sole continuous member of Los Angeles-based bands Suicidal Tendencies, Los Cycos, and Infectious Grooves. He has also released several solo albums under his nickname Cyco Miko. Muir's trademark is wearing bandanas, jerseys with the number 13, and hats with block-style letters that read "suicidal".

"Institutionalized" is the debut and only single released in 1983 from the eponymic debut album by American hardcore punk/crossover thrash band Suicidal Tendencies. It is one of the band's most popular songs and has remained a live staple since it was first played in 1982. The song was re-recorded for the band's 1993 album Still Cyco After All These Years; this version was nominated for the Grammy for Best Metal Performance in 1994, but lost to Ozzy Osbourne's live version of "I Don't Want to Change the World".
