Fivio Foreign Gives Disastrous Brooklyn Nets Halftime Performance

Fivio Foreign was excited to bring his hit singles to the Brooklyn Nets season opener at Barclays Center ... but something was clearly off with his performance, and the fans let him have it.

Fivio took center court at halftime to deliver a medley of "Say My Name," "City of Gods" and "Big Drip" but there were apparently some technical difficulties ... the Brooklyn rapper missed the cue on most of his lyrics, resulting in a live performance of ad-libs.

Fans split the blame down the middle ... with some blaming the Nets audio crew and others just chalking it up to Fivio being a slouch on the job.

Of course, Twitter users let him have it, writing, "If you’re illegally streaming this Nets game you know that this fivio foreign halftime performance is one of the worst things in history." Another wrote, "I don’t know who fivio foreign is, but this one of the worst halftime shows I ever seen."

T.I., being the experienced rapper, noted Fivio's lack of in-ear headphones to hear the songs properly.

The glitchy performance certainly didn't inspire the home team ... Zion Williamson and the New Orleans Pelicans blew out the Nets on their home floor 130-108.
