"If I needed to record, I'd head to the coast or Nashville, one or the other"

This quote by Wanda Jackson recommends that she believes the very best locations to record music are either the coast or Nashville. This suggests that she believes these 2 places have the best resources and environment for producing music. It is likely that she has actually had positive experiences in both places, as she wants to go to either one. This might be due to the schedule of recording studios, the quality of the equipment, or the existence of other musicians and producers. It might also be because of the environment of the cities themselves, which could be motivating and conducive to creativity. Whatever the reason, it is clear that Wanda Jackson believes that the coast and Nashville are the best places to tape-record music.
