Quest of finding bigger copycat!!

I was once amazed by performance of the band Khruangbin which is an instrumental trio...

Then I saw KEXP with band BALTHVS and then I saw KEXP showed Glass Heads.

Then I heard the band Nomad which is extremely rare afro-beat band from mid-60's.

Khruangbin band is active since 2009 picked up the vibe of the band Nomad.

The question is who among these mentioned bands the biggest copycat? Their styles are extremely similar.
