Experiment all you want, but you have to retain some element of what made you famous in the first place, or you lose your soul.
+1. I totally agree with that.
Why people still confuse body with soul, material with spiritual is beyond me.
You can change the style keeping, or sometimes to keep the soul.
Read this Bob Dylan quote from Madagas's informative post.
Q: Do you worry, that the latest rash of awards and acclaim will make
the media start focusing on you again?
BOB: No, that time has passed. Once they move away and lose track of
you, they'll never catch up with you again. They're off searching for
someone new to put a label on.
BOB: I know there are groups at the top of the charts that are hailed as
the saviours of rock'n'roll and all that, but they are amateurs, They
don't know where the music comes from . . . Soul is where the music comes from. Not the genre nor the format of the band and the music, let alone the label the media puts on them. Geez.
