The Fenix Underground has been a staple in the Seattle scene for many years. After the earthquake in 1996 it was moved to it's current location in Occidental Park. Since the move it has struggled to find an identity among the clubs in the joint cover group.
Sometimes goth (Moonday) sometimes techno (Fri and Sat Downstairs) and sometimes uncertain. Depending on WHEN you visit the Fenix will largely determine what kind of experience you have there. Generally they have some kind of live music upstairs on the weekends but it is very hit or miss. Most of the time you will find bands you thought long dead playing the stage (Berlin for example) or local rock acts who THINK they are the biggest thing since sliced bread but have yet to grip the reality that they are now 40 and have not made it yet.
Thursdays are the highlight of the week with the weekly Bedroom Club by local starlets Burning Hearts Burlesque. This is the one night it is okay to just sit back have a drink (overpriced) and watch a true show. Most nights though, you are really gambling by walking in the door.
It is a great club, well designed, very interesting interior, but is struggling to find a modern voice. Worth a visit, at least to see what it looks like to spend millions on a new club. Oh and they do have the free pool downstairs!!
