''Mother's Milk'' instantly garnered more attention than the band's previous records and, as such, the venues the band performed in were able to accommodate far larger crowds. For the first time the band also upgraded to a full-fledged tour bus and added backup musicians and singers. Longtime friend,
Keith "Tree" Barry was added to play horns and backup singers
Kristen Vigard and
Vicki Calhoun (who appeared in the video for "Knock Me Down") also joined the tour. When the band hit England, roadie
Robbie Allen (nicknamed Rob Rule) would open for the band providing a comedy performance in which he would pretend to cut off his own penis. Allen would later become one of the band's backup singers on the
One Hot Minute tour. The album's official launch, however, was held in
New York City at a club called Tramps; following this, Red Hot Chili Peppers embarked on an introductory European tour which included a free show in Amsterdam's
Dam Square that attracted over 10,000 attendees. By the end of the leg, the band members were having trouble adjusting to their newfound fame as virtually every concert on the tour was sold out and ''Mother's Milk
approached 500,000 units sold. Spin'' reported that following a show in
Atlanta, Flea invited a woman to his hotel room for sexual intercourse, but locked himself in the bathroom upon arriving because all he could think of were his wife and daughter. The tour continued in the United Kingdom, where the band was receiving less attention; Kiedis complained after several shows there, "We're huge in the States and it's sort of frustrating and confusing that no one knows who we are here." It was not until after their return from the UK that "Taste the Pain" was released as a single and subsequently charted at number twenty-nine there. Smith and Flea's arrest worsened Kiedis's impending charge in Virginia from the "Positive Mental Octopus" tour. He was convicted of sexual battery and indecent exposure and sentenced to pay a fine of $1,000 per charge. Once complete, the band rested, and Frusciante and Flea organized a short-lived side project called H.A.T.E. with
Fishbone vocalist
Angelo Moore and
L.A. Guns drummer
Nickey Alexander. EMI capitalized on the recent interest in the Chili Peppers by releasing a music video compilation VHS called
Positive Mental Octopus, which was named after the tour, in 1990. That same year the band also released "
Show Me Your Soul", a song that was originally a b-side on the "
Knock Me Down" single, on the soundtrack to the hit romantic comedy film,
Pretty Woman. The song was a minor hit for the band and a music video was made. For unknown reasons the band also recorded a cover of the
Bachman–Turner Overdrive song, "
Takin' Care of Business," however the song would never be released. ==25th anniversary==
