The Raconteurs (Jack White's band, he was named the 17th best guitarist of all time by the Rolling Stone), Nathaniel Rateliff and the Night Sweats, The Black Keys and Greta Van Fleet are a few bands still making music that are pretty true to their rock and blues roots. The Black Keys have more recently changed their sound though.
Other bands on the list are similar, but I'm not familiar enough with their music to classify them
