Question:

Where can I find instruction for advanced steps of tango?

I took a beginner's course last year and found it a bit too easy. Now I am too good at it. Looking for intermediate to advanced instruction online or a DVD.

Really do not know which kind.. A description, though is that you take three steps backward (right left right) and then two steps to the left (Left, together). Not sure which specific kind this is.
