Stuck for things to do on Hallowe'en? Why not lock yourself in a confined space, bar the doors, place a good strobe light in the corner, and listen to the Flaming Lips’ new 24 hour song ‘7 Skies H3’ in a single sitting. It should prove appropriately intense.

‘7 Skies H3’ is now available to stream from here, but with a limit of only 999 listeners at any one time. Otherwise, if you feel so inclined, physical copies of the rather long song can be purchased from the site in the form of a $5000 hard drive, embedded in an actual human skull. A perfect Hallowe'en gift for your loved ones.
