Ahhh Mike...Great minds...

I use it in a turnaround in my "Moon" song..

The Same Old Moon in the key of G..

Bm7flat5..E7flat5/Bflat..Am7flat5..Aflat7flat5..resolving to Gmaj7...
I know I could call that E7flat5 over Bflat a Bflat7flat5 but Keyboard guys give me a cooler voicing when I call it an E7..

Sometimes the Bass will play a D against that Aflat finisher..it sounds cool !

Jeez Mike...we sound like we know what the Hell we're talking about....they're gonna take away all our guitar club privileges !
