Well, this is disappointing: Shortly after announcing his most extensive series of American concert dates in years, Lou Reed has reportedly had a change of heart.

According to the NME, all of the shows on Reed's docket -- including his scheduled appearances at Coachella on April 12 and 19, which were supposed to serve as a sort of bookend for dates in San Francisco, Monterey, and Los Angeles -- have been canceled due to what one promoter is referring to as "unavoidable complications."

The NME's report notes that the ever-mercurial former Velvet Underground frontman recently gave one group of fans a happier surprise, showing up unannounced at a March 4 listening party for his 'Transformer' album in a New York City bar -- and even hanging around to talk about the music after the needle lifted. It's a rare example of the famously forward-looking Reed showing patience for the past; in recent years, he's dabbled in a variety of experimental arenas, including scoring a T'ai chi instructional DVD and releasing a live album with the experimental Metal Machine Trio.

Last year, Reed visited Europe on the 'From VU to Lulu' tour, raising hopes that 2013 might bring a similar series of dates for American audiences. Here's hoping those "unavoidable complications" are taken care of soon.

Canceled Lou Reed Tour Dates:
4/12 - Indio, Calif.
4/14 - San Francisco, Calif.
4/16 - Monterey, Calif.
4/17 - Los Angeles, Calif.
4/19 - Indio, Calif.
