People who weren't at the venue for the 20 songs' debut most likely won't be hearing them, at least, not any time soon. The venue apparently had enforced strict rules forbidding cell phone activity. While the audio files haven't appeared on the internet, due to the no cameras or audio recording equipment allowed, details have increasingly leaked concerning the songs West debuted.
One concert-goer in particular, Jason Powell,
revealed that the songs were "dark, hellish and groundshaking." Others described the songs as "insane" and "crazy." However, it seems to be that West was testing the waters with the new songs, and more information will become readily available concerning the new tracks from West.
