I've hit a big hitch.. im a big fan of hendrix.. so last night i learned all along the watchtower..

But.. for some reason.. with hendrix's improvs i just cant sing while playin the guitar parts.. i can sing if im jus doin the chords rhythms.. with like acoustic songs etc..

Any advice or practice suggestions that I could use to perform these songs that have hendrix-esque chord improvs with singing?

i'd really appreciate it..
