In early 2018, Lantz L'Amour and former Smack and Crenshaw Mafia Motherfuckers collaborator, "Rick" James Zimlin, formed the "Miami Vice–rock" duo, The Violent Professionals, after nearly five years of writing songs and occasional retreat experimentations with The Singing Ringing Tree in Burnley, Lancashire, England.

"It was really about making sure the material had vision, as well as a connection with ancient ancestors," L'Amour commented in an interview with The Yorkshire Guardian, "as opposed to just performing songs that were in our extensive joint catalogs not yet used in other projects.

On September 3, 2018, The Violent Professionals played a secret show (as the Bästard Säints) at The Viper Room in West Hollywood, California with American hard rock band Junkyard.

However, due to disputes and creative differences, the follow-up Crenshaw Mafia Motherfuckers record was scrapped, leaving L'Amour and Hartman to explore new material built around Himawari's drum tracks that were laid down before the CMMF breakup.

In May and August 2008, L'Amour joined ex–Miami Dolphins cheerleader, Shelby Goff, and her band Generation Beautiful, featuring Jamie Zimlin and Dylan Howard on two USO tours through Iraq, Kosovo, Kuwait, Germany, and Italy to perform for Multi-National Coalition soldiers in combat.

[2] Crenshaw Mafia Motherfuckers (CMMF) were a Los Angeles–based rock band featuring renowned Japanese drummer C. J. Himawari aka Clutch (Sex Machineguns), Lantz L'Amour, Jamie Zimlin, Stacey Blades.

The band released one CD EP, Live at the Wilcox Hotel, and played their first show at the El Centro in Los Angeles for the reopening of The Cathouse with Riki Rachtman before touring Japan in early 2002.

In late 2000, L'Amour played briefly with San Diego punk band Machinegun, founded by Chris Fields of Jon Cougar Concentration Camp, The Queers, and the Dwarves.
