I think Ozma's first ever public performance outside of their high school was at No Future Cafe late 1996. A friend of the band, big boy Robert B., happened to own a camcorder and video taped their inagural show attended mostly by their classmates, close friends and relatives of course. No one except the band members have a copy of this tape.
After several months, they played at The Whiskey for the first time. The second time they set foot on the Whiskey stage was when they opened for Weezer. IMHO their best performance ever on stage. Unfortunately, no one was able to tape this show because of weezer's strict rules. They have not played at Whiskey since then.
