Friends, My band Killer Filler is booked to play New Year's Eve for the city of Raleigh's First Night celebration. The festival uses every available stage in the downtown area, and they have put us in the sanctuary of the First Baptist Church. I haven't seen the place yet, but it's an older church with a capacity of about 425. Question: what kinds of acoustics issues will we probably deal with in there? We're a 5-piece instrumental band, so with no vocals required we'll be working without PA support. We're used to playing in bars, so I have no idea what it will feel like to be in a room that large. I've got a big rig (SVT and 810) and the guitar players have reasonably powerful combos, but the keys player runs his Hammond B-3 though an old B-15N and can run out of headroom before the rest of us do. Can you share some tips and experiences on playing a big room without a PA? Many thanks for your thoughts.
