There are several artists known as "Raz":

1.Raz is David Rasak, a rapper from Flint, Michigan. He currently performs as "Playmakaz".

2. SunDance Records is proud to present an instant classic master of psytrance, Raz. Raz is Raz Kfir from Israel , and his debut album offers us new perspectives into powerful melodic trance. His album is filled to the brim with power, ecstatic emotion and brooding atmosphere, layered with bass lines so phat you can carve your Sunday roast on them. The melodies are unique & rich and uplifting, and some also take on a distinctive sinister dark edge…producing a war inspired apocalyptic “The world is ending” vibe.
Raz chose a double album so he could showcase all his sides of musical expression.
On both discs you can expect a full power melodic journey, complete with live guitars, finishing with emotional freestyle tracks .
Get ready for this musical journey that will leave you begging for more.
