Hi, Phestus:

Maybe you have already found them, but you should already have some files of the "101 Riffs" series. At least I think they've been in the BIAB bundle since long before 2007. The one you want to look at is "101 Riffs - Blues Piano," and it should be right in the C:/BB directory.

These riffs aren't specifically for "Slow" blues, but blues is blues, although I bet I get what you mean in terms of chord substitutions, etc, so will let someone else tackle that question. This collection, which you should already have, is a great way to start, and a great way to practice chops.

Daisy.
