Twelve Bar presents the result of their latest collaboration, which features Brooklyn-born artist/actor Gregory Siff‘s unique spin on their signature logo. The release coincides with Siff’s solo show at the Siren Studios in Hollywood, CA held yesterday, March 1, from 6 – 11pm. On the front of the white tee, Twelve Bar’s famous heart logo is made up of “faces” made famous through Siff’s own blend of pop and abstract artwork along with sprays of color. The reverse has a tagged-look with “There & Back” written across the neck celebrating the collaboration, which was put together to benefit the Virginia-based non-proft, Communities in Schools, within Siren Studios’ artist series, The Rooftop Sessions. The t-shirt is being sold exclusively through the Twelve Bar website for those who couldn’t make it to the event. Check out additional looks and a sweet time-lapse video of Siff painting a mural at Siren Studios to an incredible James Brown soundtrack after the jump.
