Kanye West wants to show blood is always thicker than water ... so he hit up Travis Scott's concert to prove it.
Kanye and Kim joined the crowd -- which also included Jay-Z and Beyonce -- at Trav's Astroworld tour stop at The Forum in L.A. Wednesday night ... and Ye looked like he was feeling the music.
This comes just days after Kanye expressed his frustration with Scott -- whom he considers family -- for allowing Drake to "sneak disses" at him on his hit song, "SICKO MODE."
As you'll recall ... Kanye went on a Twitter tirade last week blasting Drake for threatening him and his family, but during the rant he also called out Travis for allowing Drake to diss him on 'SICKO.'
Specifically, Kanye took umbrage with Drake's "checks over stripes" lyrics on Trav's track ... meaning Nike over Adidas. Ye, obviously, is an Adidas man.
Kanye tweeted a day later that he and Travis met up and hashed things out ... but many thought there might be some side beef lingering between the 2.
It looks like Kanye's practicing what he preached, though -- family first and always ... and all's well with the Kardashian family rappers.
