Full disclosure: I worked at Sonic Boom when the first RSD happened in 2008. But Sonic Boom has always been the local shop to hit on RSD, with loyal customers forming lines in the early morning hours. They have a pretty wide-ranging selection of RSD-exclusive releases and fill the used new arrival bins with loads of cool and desirable used records just for that day. I am always surprised by the amount of incredible marked down records in the sale bins (I guess I have the taste for obscure records people don’t want).
