This is another place in the city where I've seen many a great band perform. Formerly the Diamond (he types definitely giving away his age), the venue was reborn as the Phoenix, rising from the ashes of, well, nothing as far as I can tell. I'm pretty sure the metamorphosis from The Diamand to The Phoenix seemed to be just some fairly straight-forward reno and a change of the sign out front. It's a large open space with a balcony and a large stage that has housed and continues to bring in some really stunning bands.
One of the key changes I suppose is the division of the place into different rooms, allowing for different types of music to be played during the night. This affords you to go to the large DJ area in the main space or find a quieter snug to chill out in. Between the main room, the Loft and the Parlour, you should be able to find a place that suits your ever changing moods throughout the night. Go on Saturdays and Edge-102 take over and play a live-to-air show from the club. Big mix of music that pretty much rubs everyone the right way.
