"I enjoyed making this album a lot because of the knowledge we acquired over the last 3 years"

In this quote, Isaac Hanson expresses his satisfaction in producing an album due to the knowledge and experience got over the previous 3 years. This suggests that the procedure of making the album was not just fulfilling, however also academic. Making use of the word "acquired" indicates that the knowledge was actively sought out and obtained, instead of passively acquired. This might indicate that the band put in a lot of effort and commitment into perfecting their craft for many years, and this album is a reflection of that growth. In general, the quote highlights the importance of continuous knowing and development in the creative procedure.
