Here's a nice line over the Bb7 chord of this great standard : The Chicken (P.W. Ellis)
The lick starts with the Bbm pentatonic scale and then uses the F melodic minor scale also known as the Lydian b7 or Lydian Dominant mode. it's basically a Mixolydian mode with a #4 or #11 (instead of the regular 4/11). Thanks to this raised 4th, it gives use a more modern 'sound' or 'color' to play over dominant 7th chords.
Enjoy / Steph
