FCC Clean! Producer/DJ based in Oakland, CA. Resident Advisor says that they produce "darkside jungle and 4-on-the-floor breakbeat-hardcore." I have no idea what this means but hope it holds value for you :)

1 (4:30) - high bpm pretty frantic track like techno with wisps of d&b. Ends with a single bass line so would be good to blend with another track at the end. Dead air from 4:12 onwards (so last 18 seconds).
2 * (5:49) - I imagine this is how it feels when you take pre workout/Adderall/meth. Definitely had me head bopping.
3 * (6:02) - pretty floating melody on top of the rhythm track. Some really cute bell-like sounds come in halfway through. I love the ending, it's like rubbing your fingers against something ribbed. The last sound echoes out so there is dead air in the last couple seconds.
4 ** (6:02) - this feels like the backing track for an intro sequence in one of the earlier fast and furious films. Very run Lola run/ speed running a game energy. This theme comes in around 3:02 that sounds like it's sampled from traditional southeast Asian music.
