In 1973, Mammoth changed its name to Van Halen. According to Roth

In 1973, Mammoth changed its name to Van Halen. According to Roth, this was his idea. He felt it was a name that held long-term identity, artistic and marketing advantages, like Santana . They continued to play Pasadena, San Bernardino, and Venice at clubs, festivals, backyard parties and city parks like Hamilton, drawing up to 2,000 people. Traffic jams and noise complaints to the local police often ensued, as far away as San Pedro. Van Halen subsequently played clubs in Los Angeles and West Hollywood to growing audiences, increasing their popularity through self-promotion, passing out flyers at local high schools. This tenacious self-promotion soon earned them a loyal local following.
