Dementia

There are at least two bands in the country named Dementia. I'll be discussing the one from Bangalore. The other one is from Delhi. While they've listed themselves as Progressive metal, they sound a lot more like groove/thrash/death metal than prog. In fact, if a casual listener were told that it's Lamb of God, he might be inclined to believe it. That's not necessarily a good thing though.

Bourbon Street

Bourbon Street are a jazz-fusion band from Bangalore. A little difficult to categorise them because they also play a little bit of blues-rock and profess to be mostly a jam band. Since their sound is more often than not a mix between jazz and rock, we'll go with jazz rock. Although they do have a vocalist, they've only uploaded an instrumental online, and some covers.
