you may have more success and a better backing track by processing the MP3 audio file through the Audio Chord Wizard (ACW) which will analyze the track for the time signature, tempo and chord progression. It will populate the chord chart with the chord progression.

With that information, you can make a backing track that will not contain any artifacts from the vocals.

You can process audio through the ACW in either Biab or Realband.

Another method is to locate a quality midi file to obtain the same information. Opening the midi file in Biab will automatically provide the key signature, tempo and chord progression. Choose an appropriate style and generate a backing track in seconds.
