Tim Durling discussed his book "Unspooled" about 8-track tapes, which explores the format's history and collecting culture while combining personal biography with music collecting. The book's creation was inspired by a conversation with recent podcast guest Martin Popoff, who wrote the foreword, and was completed through a successful Kickstarter campaign in 2021. Tim shared his extensive 8-track collection and experiences as a collector, while also discussing the format's history and popularity, including its continued production beyond the 1980s. Additionally, he promoted his other books, which focus on specific bands and artists.
