but he played Hey Joe with his teeth not the Star-Spangled banner, and his best solo is obviously "Machine Gun"
before Jimi passed away, he had a whole album about to be released, it did come out. (in 1997) So you can say he has 5 albums;
Are You Experienced?
Axis: Bold as Love
Band of Gypsys
First Rays of The New Rising Sun
Also, before his death he had a compilation called "Smash Hits" with the Experience.
