By now you've undoubtedly heard about Beyonce's "Lemonade" visual album, which was unveiled after her HBO special on Saturday.But did you know the Baltimore School for the Arts has some extensive connections to the project?Nathan Bailey, a 2003 stage production graduate from the BSA, was art director for the video for the song "Hold Up."Dontae Winslow, Class of 1992, played the trumpet in one of the songs. Winslow's focus was instrumental music when he attended BSA.And fashion designer Christian Siriano, a 2004 graduate, created a white-hued chiffon feather frock worn by dancer Michaela DePrince in the visual album.This weekend, Siriano wrote on Facebook that the dancer looked "so elegant."The school shared the news today with a Facebook post congratulating its three alums. The post has been liked more than 500 times."Baltimore's young artists are making their mark across the globe," said BSA director Chris Ford. "It's so inspiring to see BSA's alumni in stage design, visual arts and music engaged in the bold cultural statement that is 'Lemonade.'"
