Acoustic Chaos in the Liquid Lounge can get pretty chaotic. When the doors open at 9 p.m. Wednesdays there's always a line of guitar strummers waiting to sign up to grace the lighted stage. Even if you sign up early, be prepared to play late, because every host has way too many friends, and those friends have friends, too. This lounge is good for crooners of all sounds for two main reasons: The bartenders serve hump-day drink specials, and the players have a walk-in crowd to win over. We've caught the tail end of a conversation about what's the best Slo Ro song to cover. We've even experienced the rare pleasure of hearing the singers of South FM and Jibe wailing two powerful voices as one. It gets more packed as the night progresses, and the stage often gets inundated with a variety of tunes from musicians who won't be heard anywhere else in Deep Ellum. It's the hype Wednesday hangout for musicians to meet, mingle and compare chords.
