"Tusk" is the twelfth studio album by Fleetwood Mac, released as a double album on October 12, 1979, in the U.S. and October 19, 1979, in the UK. Known for its experimental sound, largely driven by Lindsey Buckingham's innovative songwriting and the influence of post-punk, the album had a production cost of approximately $1.4 million, making it one of the most expensive rock albums at the time.
The band supported the album with a nine-month world tour, during which they recorded material for the Fleetwood Mac Live album released in 1980. Despite selling four million copies—far less than the ten million copies of their previous album, Rumours—Tusk has since been recognized as a significant work, appearing on several "greatest albums" lists.
Buckingham aimed to create a distinct departure from Rumours, leading to a diverse sound that some critics described as "unleavened weirdness." The recording sessions were intense, with Buckingham experimenting with unconventional techniques. The album's artwork featured unique photography, and the band members often worked individually due to interpersonal tensions.
Overall, while initially viewed as a commercial disappointment, Tusk has gained critical acclaim over the years for its artistic ambition and innovation.
