"Sound vs. Leaf" (接触～音四人衆の実力～, Sesshoku ~Oto Yonin Shū no Jitsuryoku~) is episode 111 of the original Naruto anime.
As the first step in gaining power, Sasuke's cursed seal must be advanced to its second state. For this to happen, the Sound Four seal Sasuke into a barrel and carry him from Konoha as his seal advances. They are confronted by two nearby Konoha ninja, Raidō Namiashi and Genma Shiranui, but they eventually defeat them with their cursed seals. After carrying Sasuke for ways, the Sound Four take a break, giving the recently caught up retrieval team a chance to try a sneak attack. Eventually their presence is detected, and the Sound Four attacks them before they can make a move.
