these are mostly old stuff:

Andrea Parker - Kiss My Arp
Baby Fox - A Normal Family (this is their first album, the second one isnt that bad either...more dubby than really dark)
Beth Gibbons & Rustin' Man - Out of Season ... it's the lead singer of Portishead, sounds more like a really old soul record
Martina Topley-Bird - Anything....Tricky's vocalist/ex gf...okay maybe only a few are really dark like "Sandpaper Kisses" and "Stevie's (Day's of a Gun)"
Silent Hill 3 soundtrack - i got this with the SH3 game for ps2 (majority of the tracks are by Akira Yamaoka)
Outputmessage - Nebulae (mostly electronic, the track Approaching Skyline is the closest to the linkin park you were going after)

and Doubting Thomas - The infidel....one of my alltime fave albums (not trip hop, but dark and sample heavy)
