Bob Pfeifer was and executive with Epic Records and it was he who brought Alice to Epic for the 'Trash' album. He was probably the record executive at Epic who worked the closest with Alice during the project and was most involved in the huge success of "Trash". He went on to be the President of Hollywood Records, and was the key reason that Alice chose to sign with them around 1995.
Alice was interested in going to Hollywood Records even before 'The Last Temptation' was released because Bob Pfeifer, who originally signed Alice to Epic, was now the President of Hollywood Records. After 'The Last Temptation' was finished, Alice requested that Sony/Epic let him go so that he could make the switch to Hollywood. He just wanted to go where his friends are.

In fact, Alice never released anything on Hollywood. Pfeifer left shortly after Alice signed. 'A Fistful Of Alice' was intended to be released by Hollywood, and in fact promo copies exists with the Hollywood records logos, but by the time it emerged, Pfeifer had moved on and the album was licensed to EMI subsidiary Guardian.
Pfeifer went on to head a Internet Music company that works with Metallica amongst others.
In the late 70s/early 80s Bob (as Rob) was actually in a band himself, under the name "Human Switchboard". They released on album, 'Who's Landing In My Hanger' in 1982, and Bob also released a solo album "After Words" in 1987 before moving behind a desk at Epic.
In 2006 Pfeifer made headlines when he was accused of sexual harassment by a female employee of Hollywood Records. He had her phone illegally bugged by notorious private investigator Anthony Pelicano. When Pelicano's illegal activities were discovered in 2006, Pfeifer was also arrested (along with six other clients). This effectively ended his involvement in the music industry.
In 2014 he was in the news again, this time after his ex-wife took their son (who were in Pfifer's custody) on a holiday to Europe and never returned. Appeals went out for any news or help in finding them and eventually the children were returned over a year later.
