Roger McNamee is both a musician as well as an admin of his band Moonalice’s Facebook page. Over the past five years Moonalice has built itself from a small regional band in San Francisco, to a national touring act, and, according to Roger, “Our Facebook page has been the key way that we’ve done that.”

In an interview in Mashable last year Roger described his “5 Tips For Facebook Marketing Success.”

According to Moonalice legend, each attendee at the 4/20 show at Slim's will receive a set of 18 posters as a gift from the band! Each poster is amazing and unique in its own right, together they make for a mind blowing collection of the very best of rock poster art! There will also be an exhibit of the all 696 posters in the Moonalice series.
