Emerald City Soul Club is already three years old, and it's still one of the very best things about this city. The people are spiffed up (both vintage and au courant), the jackasses are scarce (usually), and the soul is rare and hot (one night, a DJ put on a Junior McCants record worth $16,000 for the floor's dancing pleasure). The line will be longer than the Lord, so come early and have a drink. Once you've achieved proper lubrication, get out there and shake a tail feather. (Lo-Fi, 429 Eastlake Ave E, 254-2824. 9 pm, $10, 21+.)
