I am avid concert goer. I've been to my fair share of venues in the valley, and Livewire is becoming one of my favorites due to vibe, sound system and visual capabilities.
It's a great size, holding about 1100 people between the first and second floors, so it can attract some decent bands and acts to it grace its stage. Downstairs has an open floor/ standing layout, however I've seen it be more versatile with seats, tables, a runway, etc.
This place can be a concert venue or a private events venue. Upstairs you'll find booths and seating, much like you would find in a nightclub that offers bottle service and superb viewing of whatever is happening on the dance floor and stage. You will find an adjacent patio to the upstairs bar, that allows for you to pop outside and get some fresh air.
Service is pretty quick and bathrooms are clean!
Definitely keep an eye out for acts coming though, as this place is booked with fun filled music on the regular.
