How to create backing tracks. Harp removal

When you are studying an Instrumental, if you want the backing track to practice, you may be lucky... chances are high that the Lead Harmonica on the mp3 was mixed as if it was the vocal, and sofor easy to remove (thank you David for the hint)

I found the free program Audacity (http://audacity.sourceforge.net/download/ ) and the plug in "Center Pan remover" ( http://audacity.sourceforge.net/nyquist/centerpanremover.zip ) to be an easy way to end up with an accaptable jam track of the instrumental you are working at.

If interested you may also read those instruction, just read Harp wherever is written Vocal:
