There are rooms in Santa Ana where live music works differently, and The Observatory is one of them — the kind of space where the low end hits before the volume registers. Ballyhoo! performs at The Observatory in Santa Ana on April 17, 2026. Doors at 7:00 PM, show at 8:00 PM, All Ages. The people who were there will describe it differently than anyone who heard about it later — that difference is what the ticket buys.
