I don't mix too much anymore (the 1210's are in storage at the moment
) but I do have 15 mixes recorded between 2005 and 2010 that can be found here:https://www.mixcloud.com/Rusty_Nails/
For the harder stuff, start at number 15 and work backwards. Some of the oldest ones aren't quite as hard/dark and, dare I say it, even include a bit of jump-up style stuff in places. Possibly to be avoided if you only like it dark.
If you do take a listen, enjoy!
