The threat of rain didn't keep people from Yuri's Night at Moffett Field, this weekend. The 2-day science, arts and music festival, a celebration of the first man in space, Yuri Gagarin featured many local artists and musicians including Bayonics, DJ legend Q-Bert and Primus' bass virtuoso Les Claypool. MC Supernatural showed supreme, old school freestyle skills while N.E.R.D. and Common brought the hip-hop flavors. The Black Keys topped off the night with a ballsy, blues-tainted rock finale.
