Alright, I'm looking for a cool scale to use over a I-VII-IV-V-VI progression. I'm using 7#9 chords for all of it, so the chords aren't definitively major or minor. So for all you theory heads, gimme some of that witchcraft!
Use the chord tones.

If those are the chords you're using.. I don't know how it will sound.. But if it sounds good to you, hurray!

Try the minor pentatonic of each chord over it's chord. (Emin penta over E7#9, Dmin penta over D7#9)

Same with major pentatonic, dorian and mixolydian.

For a bit more jazzy feel: altered, half-whole diminished, whole-tone.

Note that it's probably best to change the scale with each new chord, since it isn't a natural progression.
