Well, they use flamenco-style guitars, and there are common roots with flamenco music because of Spanish heritage, but the comparison stops there. I can hear a whole lot of differences. The most striking one is these two artists rely a lot on short repetitive melodic and rhythmic cells, something flamenco avoids.
You could make a similar comparison between, say, bebop and punk rock. I guess an Uzbek who would grow up with little knowledge of American culture would liken bebop and punk rock because of similarities which either don't exist, exist in a different form, or are anecdotal in traditional Uzbek music (like the drum set, bass lines, offbeat 4/4 for example).
