I found on a website (http://www.medieval.org/emfaq/misc/modes.html) 12 modes from renaissance music that at first seemed to have no point. These 12 were as follows:
Ionian- w w h w w w h
Hypoionian (mixolydian)
Dorian- w h w w w h w
Hypodorian (aeolian)
Phrygian- h w w w h w w
Hypophrygian (locrian)
Lydian- w w w h w w h
Hypolydian (ionian)
Mixolydian- w w h w w h w
Hypomixolydian (dorian)
Aeolian- w h w w h w w
Hypoaeolian (phrygian)

and the later added:
Locrian- h w w h w w w
Hypolocrian (lydian)

The "hypo" modes all start on the V of their root mode (ex. hypodorian starts on A, the V of Dorian), and the V of the "hypo" mode is the tonic of the next mode (ex. the V of hypodorian is E, the root of phrygian, the next mode after dorian). While they seem pointless at first they could find a place in a progression based on the circle of fifths, and since shredders love the modes, why not? I just thought this was interesting I don't really like to solo with the modes too much, but thats probably because a lack of a backing band to define what mode I'm in.
