Watch the Brecker Pentatonic Pattern online guitar lesson by Shane Theriot from Solo Mojo
Sometimes the same old scale sequences can get stale. I used to transcribe a lot from horn players and practice out of books that were written for other instruments rather than just guitar. Here's a nice pattern that I got from Michael Brecker, the late, great saxophonist. It works over Cmin or sounds great over the relative major Eb as well. Keep in mind when learning these examples that just a few notes from it can be very powerful- you may need only part of this in a real playing situation. Try and keep melody and phrasing in mind at all times.
