A second posthumous collection of Big Pun's work is being put together nine months after the Bronx, New York-born rapper suffered a fatal heart attack.

Previously unreleased Big Pun material will turn up on Endangered Species, a collection dubbed a "tribute" to the late rapper, according to a Loud Records press release. The album also will feature some of Big Pun's high-profile collaborations, as well as material from Pun's two studio albums.

His 1998 debut, Capital Punishment, hit double platinum sales status and sent the rapper, born Christopher Lee Rios, crashing into the mainstream.

Big Pun died February 7 after a lengthy battle with obesity. Two months later, his second album, Yeeeah Baby, arrived in stores.

Endangered Species is due to hit stores February 6, one day short of the first anniversary of the rapper's death.
