Guru and SolarFans of the late hip-hop pioneer Guru, best known for his work with DJ Premier as Gangstarr, have launched an anti-Solar website, called F***, targeting the rapper’s former business partner and producer.

Solar worked alongside Guru in his final years, and partnered with him to launch their indie label, 7 Grand Records.

Since falling ill in February, the only information released to the public was done so through Solar. He acted as his medical proxy. But, many of the statements and actions the producer had taken raised eyebrows among industry peers and longtime fans, calling into question his intentions.

Guru’s family eventually publicly stated that Solar’s intentions weren’t pure when it came to their deceased family member, claiming he barred certain family members from visit the hopsital to not telling them about his death.

The new website, F***, is documenting “Solar’s downfall … for Guru,” according to their slogan. On the website, they follow the media coverage about Guru and Solar since the rapper’s health began to decline and the controversy started.

“We started this website because we believe that there is one place for ‘Super producer’ Solar, and that is jail,” the website’s “About Us” page reads. “We are not going to sleep, rest or eat till Guru gets the proper respect he deserves. Solar is tarnishing Guru’s legacy, and we ain’t going to let that happen! Solar, you better start praying, because we are going to follow every step you make.”

In their most recent blog entry, the website posted a radio interview Solar did with Conspiracy World Wide Radio, in which they say he freezing up and contradicts himself many times throughout. Visit the website at F***

Guru died on April 19th following a year-long bout with cancer. A public memorial is scheduled for July 17 to commemorate what would have been his 49th birthday.
