The first one would be dBridge, a drum&bass artist from the UK with nice clear beats and that velvetsmooth bassline. I picked him up from Two Fingers' twitter (Joe 'Doubleclick' Chapman runs it) where he stated that track like "Seven Year Glitch" is very good for checking out a car soundsystem with its sharp synths and beats and that specific great bass frequency.... and added that one night that track had made Amon drive past the home turn and dive into the highways... The Gemini Principle is a very nice album to drive to, or just feel great to. Nighttime definitely adds a special fuel to it. I currently get weak knees from The Question. It's so_darn_immense!
The other one would go for an album by the Beekeepers, a production duo from Bristol. They are influenced by The Wild Bunch, Smith and Mighty, Portishead and Massive Attack, for example, and also the sound of the (original) dubstep (the one which concentrates more on trying out new things using sub-bass frequencies... the wobbling bass, not that one with high frequency samples).
The album is called Apiculture and it's a lovely laid-back mixture of hiphop, dub and the musical influences rolling from their home city.
I recommend listening to Sea Change, Dark Ascending and Apiculture, but the entire album is great!
