Chord of the Month
This one's wicked. It needs an F bass note and if your hands are big enough to stretch a tenth then the low A can be given to the left hand.
Technically, the chord is: F7 + (#9) (#11): that's F seventh augmented, sharp nine, sharp eleven. You might just get to hear one on Weather Report's 'Punk Jazz'. A scorching chord for synthesised brass sections everywhere.
