Watch & Learn!!!
Some really really great tutorials on here - I wish I had enough hours in the day to sit and apply everything I see and hear to my own tracks! Not watched the whole of this Jungle production course yet but the first few vids about sourcing, chopping and re editing breaks are pitched really well and give off great promise for the rest. The Paul Maddox courses are dynamite and I was also supremely impressed with Blandys Tribal and Tech House and also Frictions D&B.
