Any Massive Attack fans out there? If so, what are you listening to at the moment? Mezzanine is still one of my favorite albums.
New stuff? I haven’t been keeping up with trip-hop lately.
Older stuff (contemporary with Massive Attack’s Protection, one of my all-time faves…)? I assume you have all this but artists like Morcheeba, Olive and the Sneaker Pimps all had great records…
Both Portishead and Lamb are very good. Also check out Tricky and Goldie, and if you like a more hip-hop style, The Streets and Dizzee Rascal sort of overlap with Triphop. And for a more jolly triphop stylee, I can’t recommend Lemon Jelly highly enough.
Don’t forget DJ Shadow, DJ Spooky, Moloko, Nightmares on Wax, Kruder and Dorfmeister …
Other artists that might be interesting for you include Cocteau Twins (Beth Fraser provides the vocals for “Teardrop” on Mezzanine) and the Beta Band.
Artful Dodger (U.K.).
The Beta Band. Their stuff on the album The 3 E.P.s is deep and funky, but also light and sunny at the same time. It’s good. It’s not trip-hop, but I like it better.
Ah, Mezzanine. The CD that introduced me to music that doesn’t get radio airplay. I bought it totally on speculation off of Amazon, and it blew me away.
That having been said, check out Zero 7’s “Simple Things” CD. Another one that I bought totally on speculation, and just as good.
My most favorite, in descending order:
Nobukazu Takemura
DJ Krush
Nightmares On Wax
Tricky
Red Snapper
9 Lazy 9
Some other good ones:
As mentioned above: Lamb, Morcheeba, Sneaker Pimps
Laika
Hooverphonic
Beastie Boys instrumentals (The In Sounds from Way Out disc)
. . . will think of more . . .
Slovo are definitely worth checking out if you like Massive Attack.
Did the French band ‘Air’ make it across . . .
Oh yes, definitely Air and Lemon Jelly!
You could also look up:
Gorillaz
Soul Hooligan
Not quite as dark as Mezzanine, but still very good.
And if you liked the track “Exchange”, Blue States’ “Nothing Changes Under the Sun” is a great mostly-instrumental record.
I would recommend:
Bjork “Homogenic” and “Vespertine”
Morcheeba especially “Charango”
Tricky “Maxinquaye”
Postal Service “Give Up”
Air “10,000 Hz Legend” and “Talkie Walkie”
Nusrat Fateh Ali Khan and Michael Brooke “Night Song” and “Mustt Mustt” and the remixes by Talvin Singh on “Star Rise.” (Massive Attack has a track on “Mustt Mustt”
Tortoise “TNT” and the rest of the klangfarben group from Chicago (Isotope 217 and Sea & Cake) – more instrumental, less electronic though
Stereolab “Dots and Loops” comes closest to Massive Attack but kind of different (more drony, less dark/sample driven)
Royksopp “Melody A.M.”
Sigur Ros “Agaetis Byrjun” and their Untitled one
Thievery Corporation “Mirror Conspiracy”
For those who like the Beta Band, definitely “Hour of the Bewilderbeest” by Badly Drawn Boy.
Also, Sinead O’Connor does vocals on the new Massive Attack “100th Window” album. I like her “Faith and Courage.” Beth Gibbons of Portishead has a new solo album out but I have not heard it. Has anyone here?
I don’t think these have been mentioned yet
Amon Tobin
DJ Cam
Dusted
Herbaliser
Kid Loco
Peace Orchestra
Plastyc Buddha
Tosca
dZihan & Kamien
Cinematic Orchestra, The
cainxinth beat me to it, but I’ll say it again.
Cimematic Orchestra
Amon Tobin
Amon Tobin’s Supermodified probably falls in my top ten greatest albums ever. It’s astounding. His website will let you listen to snippets of every song off his latest full length, Out From Out Where, which should help you.
I’d also recommend This Mortal Coils album: It’ll end in tears from the same era. Lot’s of input from Cocteau Twins, Dead Can Dance members etc.
If you like Cocteau Twins, Stereolab, Portishead, etc., try out Broadcast.
I love MA, and the genre formerly known as Trip-Hop. FWIW, here’s what I listened to over the last week:
100th Window
Talvin Singh - Back to Mine (4-5 times)
Nitin Sawhney - Beyond Skin (2-3 times)
The Golden Palominos - Pure (my favorite album)
Lovage - Music To Make Love To Your Old Lady By
Soma Sonic - Future
Sounds From The Ground - Kin
Mono - Formica Blues
Emiliana Torrini - Love In The Time Of Science
Funki Porcini - Hed Phone Sex
Death in Vegas - Dead Elvis
Alabama 3 - Exile on Coldharbour Lane
Chilled Ibiza (various artists)
Dido - Life for Rent
FC Kahuna - Machine Says Yes
Everything But The Girl - Like The Deserts Miss The Rain
The Cruel Sea - The Most
The Mavericks - Trampoline
Ruby - Salt Peter

Thanks for that. Some stuff I have there, and quite a lot I’ve never heard. I’ll bookmark this thread and try to work my way through. 
I have quite wide tastes in music these days, I mention Massive Attack and specifically Mezzanine as its a paticular favorite.
The last album I bought was Songs For My Funeral by Nostalgia 77. Very Jazz influenced, with hardly any vocals, so certainly not to everyone’s tastes. If you’re interested, you can listen to 3 complete tracks here. (Realaudio needed).
I’m a Massive Attack fan, but at the moment I’m listening to the new Kanye West and the new Liars stuff. Not very similar.
Unfortunately after its '90s hey day, trip hop didn’t really go anywhere. I’m always loath to write off a genre, but it really seems as if the best of trip hop has passed us by. Portishead seems to be on a permanent hiatus, Massive Attack released the uninteresting 100th Window (though I suppose it can be used as background music in cafes). Lamb are just doing the same thing over and over and Beth Gibbons solo album was rather disappointing. The whole thing seems to be sinking into that marketing black hole known as “chill out” (which doesn’t seem to be anything, since your average chill out comp contains a soporific collection of jazz, electronica, trip hop and pop). When Dido is a leading proponent of a form of music, it’s pretty safe to say it’s dead.
Though, really, it’s a pointless rant. To redeem myself, I’ll suggest the Notwist. It’s not extremely similar to Massive Attack, but I think a fan of one should be the a fan of the other. Same mood, same collision of the organic and the electronic (though the Notwist’s beats are glitchy, whereas Massive Attack’s were hip hop).
