Pre-scoring (プレスコ) is a technique that recordings are made before the animation. Most western animations adapt to this technique, while as Japanese animation prefers after-recording (アフレコ).

Here's a list of Japanese animation that sorely used pre-scoring technique throughout the entire production. As this technique doesn't require actors to follow Sakuga (作画), actors are able to deliver the lines with more organic approach without the constrain of timing. (They still follow the scripts though, but timing is less constrain compare to after-recording). Often times, this technique allows actors to display their best acting skills, which is why few sound directors like to explore this technique every now and then. Though, after-recording is still mainstream in modern anime industry, considering the fact that fast-paced production is in favor.

Hope this will give you an interesting perspective when looking for anime recommendation!
