When somebody who was played by Justin Timberlake in a Hollywood movie decides to throw a party, the expectations are pretty high.

And Sean Parker, the man behind free music-sharing service Napster and an early Facebook advisor, clearly likes to give people what they want.

Parker, who is an investor in the music service Spotify, pulled out all the stops in a post-Facebook developers conference party on Thursday that was a cross between a backstage concert pass and Trimalchio’s feast.

The party was reminiscent of the dot-com boom era in the late 1990s, when extravagant blowouts thrown by well-funded startups were practically a weekly event.  A decade later, Web company valuations are on the rise again, led by companies like Facebook, Groupon and Zynga, and talk of another tech bubble is in the air again.

This time around of course, the broader economy is sputtering and unemployment is stuck at 9.1 percent. But Parker’s party, which took place in San Francisco’s Potrero Hill neighborhood, underscored the euphoric atmosphere among the engineers, executives and venture capitalists in the Internet industry.
