Reply to WHERE did you learn to PRODUCE?

Production is something many want to delve into, but few know how. My question is where and how did you personally learn music production from? And how long before you considered yourself 'good'?

Did you...

• Have a mentor/friend teach you?
• Pay for classes (ie. Sonic Academy)?
• Trial and Error?

It seems like production is a lot of guess work and "one step forward, two steps back".

ALSO, I was hoping everyone could post links to blogs/YouTube videos and offer resources to help other DJTT members.
