There are / were at least 2 bands going by this name.
1) Blues-based, Led Zeppelin inspired metal that should have made Tora Tora a household name, but sadly didn't. One of the best-unknown bands in the hard rock genre, but lack of label support killed any chance the band had for massive success.
Formed in Memphis, Tennessee, by Anthony Corder (vocals), Keith Douglas (guitar), Patrick Francis (drums) and John Patterson (drums). They quickly beat out sixty other groups in a Battle of the Bands contest and received some free studio time.
