A former Enron pipeline engineer going by the name NRun is releasing a rap album, Corporate America, that lambasts his former bosses by name.

NRun, whose real name is David Tonsall, lost his job after Enron's collapse into a record bankruptcy in 2001.

Tonsall said he was angry that the Enron criminal investigation was taking years and had yet to name anyone higher up the corporate ladder than former Chief Financial Officer, Andrew Fastow.

Now frustrated Tonsall decided to vent his feelings through the rap album, which has so far cost him $15,000 to make.

"I know you can't go postal. That ends up putting you in jail," said Tonsall, who now runs his own engineering firm, Synergistic Techneering.

He jokes that he went "from pocket protector to hard-core rapper," in a sly reference to the plastic shirt-pocket liners that are the bling-bling of the engineering set.

Neither Lay nor Skilling, both of whom are under investigation by federal prosecutors, has been charged with a crime. Lay, who was Enron's chairman, and Skilling, its ex-CEO, have both denied any wrongdoing.

The title track takes Lay to task, saying Enron's failure under his watch made a mockery of the values of respect, integrity, communication and excellence that he espoused.

NRun turns up the heat on Skilling in another song: "Skilling, going to find you rain, sleet, or snow. When justice comes around, you're going to get hit."

The record is due out in December to mark the two-year anniversary of the massive layoffs that followed Enron's Chapter 11 bankruptcy filing.
