Honest answer: no one, really. No one else sounds like the Sisters sound
now.
There are some Tiamat tracks (Brighter Than The Sun is the closest I've ever heard to someone sounding like current Sisters, complete with dodgy English-as-a-second-language-Eldritch clone lyrics
![Laughing :lol:](./images/smilies/lolol.gif)
), and Paradise Lost get close on occasion, especially on One Second.
Katatonia is good, but more Tool-meets-Cure than Sisters. Too mellow and sad compared to the Girls' ballsier rock approach.
The first two Tomahawk albums (self-titled and Mit Gas) and The Tea Party's Transmission, Triptych and Interzone Mantras would probably go over well with fans of the Sisters' current sound. Porcupine Tree is way too prog-flavored, but they've got a similar vibe and rock guitar-meets-electronics thing.
Left at the dead badger.
