For Nathan, this sends a clear signal about how the company did in the fourth quarter.
"You don't go and lay an egg a couple weeks after you have Metallica play at a corporate party here, I'm just going to say that," Nathan said Monday on CNBC's "Fast Money."
But not everyone believes that the presence of metal gods presents the best reason to get into the stock.
"I don't think that there's anything to read into that," said Joel Fishbein, who covers the company for BMO Capital Markets.
"They had these guys booked nine months or a year in advance," and Salesforce frequently hosts big concerts, the analyst said.
Nevertheless, Fishbein expects the company to report "a great quarter," and wrote in a Tuesday note that Salesforce is his "top large-cap growth recommendation."
The options market is implying a 6 percent move on earnings for the stock off of earnings, according to Nathan, who does not have a position in the company.
A Salesforce representative declined to comment, noting that the company is in a quiet period ahead of earnings.
