Billy Martinez began his career in the early 90's as a freelance artist debuting his original comic series Wildflower in 1993 for Sirius Entertainment. Soon after he would write and illustrate books and stories for companies Peregrine Entertainment, Top Cow, Image Comics and Heavy Metal Magazine. In addition to his work in comics, he supplied artwork for Family Guy and Hellboy through Inkworks trading card company. In 1999 Billy formed Neko Press Comics and Publishing. The company went on to kickstart the careers of many up and coming artist and was a platform for Billy to continue to self publish his flagship titles Wildflower, Kickass Girl and graphic novels The Deepest Dark and his how to draw companion books In your Face and Body Movin'.
During this time Billy became interested in painting live at various clubs downtown in San Diego. There he would create 3 to 4 images simultaneously with bands and DJ's such as Z Trip and Red Sonya on stage. He would sell his finished pieces right on the spot. It was a new and fresh avenue to get more individuals aware of the art scene in the San Diego and Los Angeles area. Through the years his art has been featured for Starbucks Coffee Company and in various galleries throughout the United States. He currently instructs and teaches art classes that range from sequential art to fine art painting and continues to create murals and performs live art shows throughout the country. He currently resides in Nashville Tennessee where he performs live art in Nashville's historic Printers Alley and many venues throughout Music City.
