I always wanted to learn how to do this stuff are there any sites to teach someone real delta slide

Me to...I would love to learn that Delta Slide stuff ..picking etc...help

Arlen Roth has a very good book on slide. You can also check the following links (I am not sure if they all contain slide lessons).
Also, “The New Transcriptions“ of the music of Robert Johnson are amazing (although difficult to master).

I have to disagree with some of the statements from the first link (i.e., to me glass sounds warmer than metal), but as they explain, it is a site for beginners, and there’s always something to learn everywhere.
