The posse is in effect, as Buckcherry will perform a benefit show, dubbed Aidan Has a Posse, with a gaggle of guests on Thursday, August 11th at 8 PM. The evening will be hosted by New Jersey-based comedian and renowned 'That Metal Show' host Jim Florentine and will be held at the Music Hall of Williamsburg in Brooklyn. So the event certainly will be intimate. In addition to music performances and comedy, a silent auction will be held, featuring works from street artists like Shepard Fairey, Ewok, DickChicken, motorcycles from Indian Larry and much more.

The bands and artists are forming the posse that helps Aiden Seeger, a 6-year-old boy suffering from Adrenoleukodystrophy, or ALD. ALD is a brain disease that severely affects neurological signals, swiftly and irreversibly destroying nerve cells. While there is no known cure, bone marrow transplants have been known to stop the degenerative process.

In order to help Aidan in other ways, besides raising funds, there will also be painless cheek swabbing on site to build a bank for bone marrow donors, a crucial element in the fight against ALD. If you go, be sure to get swabbed.

In a statement, Buckcherry guitarist Keith Nelson said, "The Seeger family has been friends of ours for many years; it has been devastating to learn about Aidan's recent diagnosis of ALD. With the family's blessing we quickly put together an event in Aidan's back yard, Brooklyn, NY, to raise both awareness and financial support for the upcoming battle Aidan will be facing. We are grateful for the long running friendship of the Seegers and fortunate to be in a position to lend a hand. The initial response has been overwhelming with Bowery Presents, Flying Television, Shepard Fairey, Ewok and many others already jumping on board to help. It will be a night to remember."
