Sean Merrick, also known by the monikers HDV, H-Bomb, Jacky Jasper and Hollywood Street King, is a rapper and former celebrity blogger. Merrick's catalogue of artistic works showcases features from artists including Ike Turner, Rick James, Roger Troutman, Bootsy Collins, Ohio Players and The Brides of Funkenstien.

In 1991, as the artist formerly known as Toronto rapper HDV, the "Pimp of the Microphone" emcee made a historical contribution to the revolutionary Can't Repress The Cause Movement.

In 1993—three years before the 1996 release of Tupac's Jesus-inspired Makaveli album cover captioned, "In no way is this portrait an expression of disrespect for Jesus Christ,"—Jacky Jasper marked the release of his album debut as HDV—an acronym for 'Higher Deeper Values' -- with a socially-charged, Jesus-inspired key art album cover that depicted him nailed to the cross above a shocking pictorial of references to the KKK holding up a sign that read "N***ers DIE", alongside a sketched-portrayal of an angry nationalist-feminist-type caricature holding up a sign that read "chauvinist pig!". The fearless visual art statement was the cover that packaged the raw "pimp of the microphone' street-prose of lyrical content presented in rhyme that solidified the artist formerly known as HDV's pioneering role as the first Toronto rapper to openly address the systematic effects of political colonization, racial discrimination and economic oppression -- that he witnessed in Canada, and thereby introduced to the Canadian media and socially conscious Toronto hip hop movement. However, despite the raw and innovative artistic expression contributed to Canadian music, the artist formerly known as HDV was promptly blacklisted in Canada and quietly censored off music store shelves (including Sam The Record Man).

In 1994, Higher Deeper Values, the album, was released thorugh ISBA Records/Sony Records. Recorded at Toronto's Wellesley Sound Studios, album features the productions of Toronto-based music producer Phil Cold and Toronto rappers K-4ce, 10K and Kevin "Ice" White.

In 1996, after being recruited by Eric B to serve as a valuable contributor to the American rap music movement, the censorship of HDV would turn to a situation best described as being a case of that which Canada shunned, American rap innovators recognized and welcomed.

In 1997, H was invited to record his next album in America. The NYC-LA bi-coastal studio production led to the artistic reinvention of HDV to H-Bomb dropping the 1998 studio album titled Narcissism -- a 15 track album featuring Ice T, Coolio, Kool Keith and Domino. The title track of the Narcissism album "Playaz Need No Love," featuring Roger Troutman, charted on Billboard's Hot Rap Tracks for 1999 and peaked at number 33.

In 1998, H Bomb and Roger Troutman co-starred in the Las Vegas film production of "Playaz Need No Love," the official music video.

In 1999, H Bomb introduced the new moniker 'Jacky Jasper' when he teamed up with Kool Keith for the album First Come First Served. The track titled 'Call the Cops' off the First Come First Served album, which featured Jacky Jasper as an uncredited vocalist, was later listed in the movie soundtrack for the 2006 film titled Grandma's Boy.
