Buckethead has many albums! Very prolific artist. You've probably heard some things, just didn't know it was him.
It's easy to get lost in his catalog of releases. Goes from melodic to quite heavy. Although I have to say, Pike 65 is my favorite. I listen to it at least once a week at work, slaving at my desk for the man.
If you need some suggestions, just hit me up. I think he has close to 200 albums right now.
