Pretty sweet. They were described to me as "slightly-harder drum and bass", which worried me a little, since I didn't know if I would be up for something heavy, but either it was only slightly-harder, or I don't know how hard regular drum and bass is, or I ended up being in a heavier mood than I thought I was, because I thoroughly enjoyed the album. It sort of drifted into the background, which is exactly what I'm hoping for when I listen to music at work.
I'm not entirely sure what else to say here. I suppose I could add that they didn't seem as minimal as the Plastikman/FUSE albums I've got, and they were a lot less sample-heavy than Mushroom Jazz by Mark Farina, but I don't think that really tells you much about the music itself. Hopefully, with more exposure to some quality drum and bass, I'll be able to give more informed opinions, but for now, I guess this will have to be my baseline for future reviews.
Oh, one more thing, the next few reviews might run a little late, because even though I've listened to the music, I only have a couple of hundred words written about each of them, and I'm guessing that it'll take some re-listening to think of more things to say.
