Tomorrow, April 19, is Record Store Day, and Jaco Pastorius figures prominently.

First up, we have a new Jaco Pastorius album release, available tomorrow only at participating independent record stores. I have no idea if the stores where I live will participate, but I’ll be checking it out.

The new release is Modern American Music… Period; The Criteria Sessions. The album contains the demo tracks that Jaco made in 1974 at the age of 22, which have either never been officially released, or previously released only in edited form. These tracks — with drummer Bob Economou, pianist Alex Darqui, steel drums players Othello Molineaux and Sir Cederik Lucious and percussionist Don Alias — led to Jaco’s first album, and you hear the early “demo” versions of many of the songs that Jaco later recorded. John Kelman of All About Jazz has a lengthy review.

In addition, Metallica bass player Robert Trujillo’s long awaited documentary about Jaco is the official film of Record Store Day, although it isn’t expected to be completed until late this year. You can hear Trujillo talk about Jaco and the documentary in an NPR interview that was published today. You can also follow the progress on the film at their Facebook page.

And finally, Jaco is the subject of the official Record Store Day poster (pictured above), which will be given away at select stores while supplies last. For more information, see the Record Store Day news release about Jaco.

Update: My local record stores did participate, and I saw both the CD and vinyl album at the stores. Didn’t see any posters, although by the time I made the rounds they may have already been taken.
