Channeling your inner, petulant teenager into the music of your chosen genre, is a good way to go, just not this way.
Happens to us all, do something else and come back to it.
*You know this of course.
Ultimately, you need to make it your interpretation, rather than a slavish copy of PP’s line. One of my fave tunes to play is I’m Gonna Tear Your Playhouse Down (that pesky Pino again), there are some things that I just can’t do smoothly (the outro for instance), so it has to be an ez version. Vultures is another sneaky tune from that Mayer album.
