The temperature may have been about 70 degrees Saturday evening at Montanafair, but boy band 98° heated things up with a musical performance in the First Interstate Arena.
The video shows the band singing their 1998 song "Heat it Up."
98° has sold over 10 million records worldwide and has had 8 top 40 singles in America.
Unlike other boy bands of the era, 98° was formed by its members, rather than assembled by a producer.
Sunday, Old Dominion takes the stage as the third musical act at Montanafair.
