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 melody 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.
