After shuffling through drummers during their more than 25-year career, Primus singer and bassist Les Claypool and guitarist Larry “Ler” LaLonde are reuniting with their first drummer, Jay Lane, who left the band before their first album was even released. The group gained mainstream success with tracks “My Name is Mud” and “Wynona’s Big Brown Beaver,” and made their mark on TV, penning the theme song for South Park. With their cocktail of thrash-funk, alternative and metal, the band has been named an influence for metal acts like Korn and Limp Bizkit. The Dead Kenny G’s and gypsy-punk band Gogol Bordello open for Primus at the Williamsburg Waterfront on July 30. 5:30 p.m. $36.50.
