Shellshock first came to national attention with Crazy Town's hit 2001 single "Butterfly." At rap-metal's absolute peak, the seductive ballad was hard enough for rock stations but still catchy enough for pop radio, topping Billboard's Hot 100 chart and reaching #1 in six other countries. The third single from the group's debut The Gift of Game, it gave their then-almost 18-month-old album a second life and catapulted the group to worldwide stardom.
Shellshock first linked up with his partner in rhyme Bret "Epic" Mazur in the mid-'90s. By 1999 they had expanded into a full band and dubbed themselves Crazy Town. One of the most successful groups of their era, they toured with several festivals and made tracks with rap legend KRS-ONE and Weezer's Rivers Cuomo.
After "Butterfly" and two albums, the group went on hiatus. Shellshock quickly had his second international smash with "Starry-Eyed Surprise," a collaboration with English trance DJ Paul Oakenfold. The single had several resurgences throughout the decade, thanks in part to its inclusion in commercials for Diet Coke and the Apple iLife.
"Starry-Eyed Surprise" gave Shellshock enough momentum to release a proper solo album. Reemerging as just "Shifty" on 2004's Happy Love Sick, he scored a minor hit with "Slide Along Side." Crazy Town eventually reformed in 2007 and returned to the stage in 2009 with new material occasionally popping up unannounced on their MySpace page. In 2010 Shellshock formed another solo project, Shifty and the Big Shots.
