Willie Nelson is releasing a jazz instrumental album to be available as a limited release on his official Web site. Set for April 29 release, Nacogdoches takes its name from the East Texas town where it was recorded five years ago. Nelson's friend and mentor, Paul Buskirk, planned the session and played mandolin in the group backing Nelson on the 19 tracks, including "Stardust," "How High the Moon," "Walkin' My Baby Back Home" and "San Antonio Rose." Buskirk died of cancer in 2002 at age 78. Noting that most of the songs were recorded in one take, Nelson tells the Tyler (Texas) Morning Telegraph, "This is a labor of love that a label probably wouldn't be willing to release."
