During Led Zeppelin's first tour of the United States in December 1968, Bonham became friends with Vanilla Fudge's drummer, Carmine Appice. Appice introduced him to Ludwig drums, which he then used for the rest of his career. Bonham used the longest and heaviest sticks, which he called "trees". His hard hitting was evident on many Led Zeppelin songs, including "Moby Dick" ("Led Zeppelin II"), "Immigrant Song" ("Led Zeppelin III"), "When the Levee Breaks" ("Led Zeppelin IV"), "Kashmir" ("Physical Graffiti"), "The Ocean" ("Houses of the Holy"), and "Achilles Last Stand" ("Presence"). Page let Bonham use a double bass drum in an early demo of "Communication Breakdown" but scratched the track because of Bonham's "over-use" of it. The studio recording of "Misty Mountain Hop" captures his dynamics, similarly exhibited on "No Quarter". On cuts from later albums, Bonham handled funk and Latin-influenced drumming. Songs like "Royal Orleans" and "Fool in the Rain" are examples, respectively displaying a New Orleans shuffle and a half-time shuffle.
