Seth Brooks Binzer (August 23, 1974 – June 24, 2024), better known by his stage name Shifty Shellshock,[10] was an American rapper and singer-songwriter who cofounded the rap rock band Crazy Town, known for their hit song "Butterfly".

Binzer struggled with addiction throughout his career and appeared on the reality television series Celebrity Rehab and Sober House.

Binzer met fellow Crazy Town frontman Bret Mazur in 1992; they started collaborating under the name The Brimstone Sluggers.

In an interview with Rolling Stone magazine in the US, Binzer said that the track was created after the pair met at a Crazy Town show.

In a video interview with TMZ.com, Binzer stated the disturbance was simply a noise complaint, and that the outstanding warrant was for counter-assaulting a security guard who was using unnecessary force when trying to throw him out of a club.

Binzer was arrested in February 2012 for battery and cocaine possession, and sentenced to three years' probation; his relationship with Lennard ended shortly thereafter.

His sobriety was short-lived and subsequently he appeared briefly towards the end of Celebrity Rehab 2, where Dr. Drew and Binzer's sponsor retrieved him from his hotel room where he had been using drugs and brought him to the Pasadena Recovery Center.

In July 2008, while shooting scenes for the show, Binzer walked out on production and into a heavy relapse after feeling insulted at a club.

On the show's final episode, Binzer is shown in the preliminary stages of being signed to a record producer for a new song, and resolves to stay sober.

[34] On the August 30, 2009, episode of Loveline, Dr. Drew gave an emotional eulogy to his good friend and Binzer's former bandmate DJ AM, who had died two days previously from an accidental drug overdose shortly after breaking 11 years of sobriety.
