Something you might have forgotten about RETNA, for the Street Cred show at Pasadena Museum of Art he covered the buildings entire facade. Baller. He also made his NYC debut, making the Big Apple stop one on his Hallelujah World Tour. The Seventh Letter Artist also released some awesome product too. RETNA's star will continue to rise (he was on this list last year, and will likely only get bigger in 2012).
