Hundreds, if not thousands, of fans are already lined up outside of Oracle Arena in Oakland in advance of the big BTS concert tonight.

ABC7, this newspaper’s media partner, captured images of the line outside Oracle Arena early Wednesday morning.

Many of the fans in line already have tickets but are waiting to get a good spot in the first-come, first-served general admission floor area in front of the stage, according to ABC7. The line reportedly started Monday.

The line likely will get even bigger as the day progresses.

Yes, the BTS Army has arrived in town.

Just imagine what it’s going to be like when BTS, the South Korean boy band that has taken the music world by storm, finally hits the stage tonight in Oakland.

Tickets for the show are long sold out. And the secondary market is doing banner business on BTS’ entire North American Tour.

The Oracle date ranks as the top Bay Area show on Stubhub, in terms of average resale price for tickets. Stubhub is getting an average of $421 per ticket, which well outpaces every other local show.

In comparison, the Eagles show at AT&T Park on Sept. 20 comes in at No. 2 on the list and is getting an average of $251 per ticket. The Beyonce and Jay-Z gig on Sept. 29 at Levi’s Stadium ranks third, with an average of $201.

“BTS have continued their record breaking streak by achieving Most viewed music video online in 24 hours with the music video for their latest release ‘IDOL’ accumulating more than 45 million views during its first day on YouTube,” according to Guinness World Records.

Taylor Swift previously held the record, having reportedly garnered 43.2 million views in a 24-hour period for her “Look What You Made Me Do” video in 2017.

BTS is a seven-member South Korea boy band, consisting of Jin, Suga, J-Hope, RM, Jimin, V and Jungkook. The K-pop act got its start in 2013 and has grown more popular with each year.

The band’s name is actually “an acronym for the Korean expression Bangtan Sonyeondan, meaning Bulletproof Boy Scouts,” according to ET Online.
