Sen Dog

On September 30, 2008, Sen Dog released his first solo album, Diary of a Mad Dog, seventeen years after the release of the first Cypress Hill album. In an interview with HipHopDX, Sen Dog described how he felt that he had more control and could talk about personal aspects of his life with this album. He said, "With Cypress, I never really felt that comfortable to put personal aspects of my life into the music. It feels good to have the opportunity to be the quarterback, if you want to call it that, in the studio, and be creative. I definitely found that I had more in me than I thought I did." He said that he wanted to have fun with this album and that he has tried out a lot of different types of music but had no agenda for the type of music on Diary of a Mad Dog. "We’ve done the whole dark, morbid thing. The rock n’ roll crossover; just a lot of things. I’m not going to have an agenda on this; I’m going to jam and record whatever is fun to me."

In the late 1990s, Sen Dog took a leave of absence from Cypress Hill to develop a new rock/rap band called SX-10. He wanted the band to have a funk sound with Latin influences. SX-10 released an album in 2000 called Mad Dog American. In 1996, he performed "Quien Es Ese Negro (Who's That Black Dude)" with Mellow Man Ace, MC Skeey, Mr. Rico, and DJ Rif for the AIDS benefit album, Silencio=Muerte: Red Hot + Latin, produced by the Red Hot Organization.

In the 1980s, Sen Dog was affiliated with a Bloods gang set known as "Neighborhood Family", and later introduced B-Real into the set before B-Real was shot in the lung in 1988. Sen Dog is known to be an avid marijuana smoker and Cypress Hill has made songs about the use of marijuana, including "Legalize it", "I Wanna Get High" and "Hits From the Bong". Sen Dog and B-Real were childhood friends and Sen Dog gave B-Real his first joint when Sen Dog was 17 years old. In an interview with Entertainment Weekly Sen Dog said, "Pot got a bad name with the flower children of the '60s, and then all these hard drugs came in, and people started dropping like flies. Today, people want to get high on something that's not going to give them a heart attack, like speed or crack."
