This mode is the same as the Lydian mode, except that it has one alteration to it, which is that the perfect 5th is raised to make it an augmented 5th. This mode, along with the Ionian #5 is a good choice to use over maj7#5 chords.

1-2-3-#4-#5-6-7-8-9-10-#11-#12-13
By stacking 3rds above the root, we get a series of Major chords:.
1-3-#5= Augmented Triad
1-3-#5-7= Major 7#5
1-3-#5-7-9= Major 9#5
1-3-#5-7-9-#11= Major 11#5
1-3-#5-7-9-#11-13= Major 13#5
Listed below are some other major chords which this mode can be used over but these do not contain the #5. In a lot of these, the #4 of this mode has been enharmonically spelled as a b5 which gives us the altered major chords that are used most often.
1-3-6= Major 6
1-3-6-9= Major 6/9
1-3-b5-7= Major 7b5
1-3-b5-7-9= Major 9b5
1-3-b5-7-9-13= Major 13b5
Lydian Augmented Vamp: The basis of this mode is in its Major tonality. The #4 and #5 are the "character" tones. The chord vamp here stresses these tones.
Vamp #1: (Amaj7#5/Amaj7b5) (Use A Lydian-Augmented. All black dots on A)
