Watch the Hybrid Picking online guitar lesson by Dave Celentano from Classical Concepts for Rock Guitar
The backing track is in drop D tuning and uses the power chords F5 - G5 - D5 - Ab5 - G5 - D5 to create a heavy swamp groove. Use this backing track to rehearse your hybrid picking ideas. Start with a simple D minor pentatonic idea like the one demonstrated in the video. Develop your idea by repeating it a few times to get comfortable with how it sits over the groove. As you get more comfortable developing ideas try making longer phrases.
