Krog, known professionally as Krog on the Rocks, was a 24th century alien musician who played the vibe tubes. He was a devotee of Vulcan meditation and logic, in his ongoing pursuit of "inner chill".
Krog was T'Lyn's favorite musician, whereas Beckett Mariner dismissed him as a "novelty beach crooner".
In 2382, Krog was scheduled to perform on the cruise ship Cosmic Duchess. He was among those engulfed by the Glumpus, a rogue nanite cluster, and was released unharmed after an away team from the USS Cerritos disrupted the nanites' control signal with his vibe tubes. Afterwards, he met T'Lyn, and they professed their mutual admiration. D'Vana Tendi later obtained his autograph as a gift for T'Lyn. (LD: "The Best Exotic Nanite Hotel")
Krog was voiced by Marcus Henderson.
Krog's species was not named in the episode, but he was identified as a Brikar by the episode's director, Brandon Williams. [1]. However, Star Trek: Lower Decks showrunner Mike McMahan and producer Brad Winters later contradicted that, stating that he is a member of a different rock-like alien species. [2] [3]
