So, if you don't already know KONGOS -- the awesome, rootsy alt band from South Africa -- you need to get on the fan train right about... now. Allow us to give you a boost... by converting you into a full-fledged believer in these four bros, one by one.

KONGOS recently took the stage at Austin City Limits, where they performed songs from their new (in the U.S.) record, Lunatic. The guys kind of blew up in the States with the release of their single, "Come With Me Now," which became the fastest rising top 10 debut on Billboard's Alternative chart since Lorde's "Royals." If you think you've never heard this jam before -- well, you're wrong. You have. We all have. And it's awesome -- as are the rest of the band's tunes. VH1 even named them one of their "You Oughta Know" acts for 2014... in case you didn't know.

Have we convinced you yet to join the KONGOS line (sorry -- SO hard to resist!)? Still on the fence? Well, let's go ahead and meet the brothers below -- via their music.

During this strutting rendition of 'Come With Me Now' let's focus on Dylan's soaring vocals... We will come with him wherever he goes.

Watch Johnny play the accordion on 'I'm Only Joking.' Yes, the accordion. It's like a modern-day sea shanty -- without all the scurvy.

Daniel brings the sweet, mellow guitar to 'It's A Good Life.'

Jesse sings, too -- oh so sweetly -- on 'I Want To Know."

Obsessed yet? We thought so! Now get yourself ALL of their tunes post haste!
