I've seen both Wu Tang Clan and Method Man & Redman at this venue and both times the experience was ruined by the sub-par sound system. I could hardly hear the lyrics and the sound frequencies were severely limited. What a complete waste of my time and money. I don't understand this mentality. Surely, the speakers are the most critical component of a live music venue?
