This third album is the only album which featured all 4 original band members - Anthony Kiedis, Flea, Hillel Slovak, and Jack Irons.It was also the first album to reach the charts at number 148. The group was persecuted by the PMRC (Parents Music Resource Center), a political action group run by wives of U.S. senators, due to explicit language on the album. Rather than hurt, this publicity seemed to help sales of the album. After the release of the album, Hillel Slovak died of a heroin overdose on June 25, 1988, resulting in Jack Irons quitting the band.
