There are a couple artists using the name Underbelly:

1. Underbelly is an electronic artist who owns a YouTube channel called You Suck at Producing where he showcases the unique production and sound design tips that he utilizes within his music. His Light The Match, Hide The Hand EP is an experimental and stylistic electronic music experience. Wowzers!

2. Underbelly is a nu metal band based in Witbank, South Africa, emerging in 2001. The band’s evolution into the 5-piece set, that has garnered a credible fan base today, peaked in 2005 after a four-year struggle to secure like-minded musicians. The band’s perseverance paid off. Underbelly forged ahead, steadily carving a niche for themselves within the South African rock/metal scene, in which they have undeniably been embraced with what can only be described as ‘moshpit’ enthusiasm. Underbelly embodies the unexpected, musically manifesting themselves with dynamic and somewhat disconcerting elements. Their sound often explodes original perceptions within the context of their supposed genre. Underbelly’s sound denies any exact classification. Self proclaimed as musically and lyrically contradictory, their elusive style was finally captured in the words of ex TUKS-FM DJ, Philip Davies:

“Underbelly’s tone is sinister, their delivery fevered and aggressive, technically exact, their songs intricately structured and impeccably timed. Typically their compositions erupt with chugging, grinding guitars, change time signatures abruptly descend into stuttering start/top techniques and swap between moments of subdued Deftonesque menace and absolute sonic disarray”.
