Also in attendance at Wednesday night’s event was Kanye’s wife, Kim Kardashian West, who documented the evening on her Instagram Story.
The reality star, 39, shared photos and videos of the cheering crowd standing in a grassy, nature-inspired installation of tall reeds and pampas grass.
Delta also posted a video in which she revealed she had also attended one of the rapper's hugely popular Sunday Services in April.
"I was lucky enough to go to Kanye Sunday Services a few months ago. It was incredible! So I couldn't wait for the album," the caption read on her Instagram story.
