Total Cost: $1,500,000 You'd think twelve albums into their career that a band would have a good idea of how to keep costs down, but apparently that wasn't true for Fleetwood Mac, whose twelfth album Tusk released in 1979. At the time of its release, Tusk was the most expensive rock album ever made, costing upwards of one million dollars. Initially the band wanted to purchase their very own studio for the purpose of recording the album, but the money instead went on decking out Studio D at the Village Recorder in Los Angeles with all the necessary equipment and software. In the end, it was revealed that the cost of the album was closer to one and a half million, and that despite selling four million copies and reaping some profit, the whole thing was considered a failure.
