Kylesa is a sludge/stoner/psychedelia/punk metal/rock entity from Savannah, Georgia. Often compared and paired with the likes of Mastodon or Baroness, their sound is quite different than any other stoner group they are compared. Kylesa started as a more straightforward sludge act, but has developed their sound with psychedelic and twisted soundscapes.
And of course you have to mention their singer-guitarist Laura Pleasants, who adds her recognizable vocals to the mix. Oh yeah, and they have two drummers nowadays.
