Robert DeLeo

I kind of combined bass stuff with some guitar stuff to achieve my sound—I've really been going nuts on eBay! I'm still trying to achieve this one bass sound I keep hearing in my head—kind of taking [Motown legend] James Jamerson's feel and mixing that with John Entwistle's or Chris Squire's sound. So it's a funky bottom, with a really aggressive top. The sound on this record is the closest I've gotten to that.

Stone Temple Pilots reunited in early 2008 and released their eponymous sixth studio album on May 25, 2010. On October 8, 2013, they released an EP entitled High Rise with new lead singer Chester Bennington of Linkin Park fame.

DeLeo and his brother, Dean, produced the 2010 Stone Temple Pilots album, Stone Temple Pilots, as well as Alien Ant Farm's TruANT in 2003.

However, Army of Anyone ended up going on "indefinite hiatus" in 2007 after disappointing album sales and Patrick's return to Filter.

In 2007, DeLeo played bass on songs for Japanese rock band B'z, including two on their album Action. He also contributes bass to five songs on their 2019 album New Love, including "Rain & Dream" which also features Joe Perry.

After Stone Temple Pilots' break-up in 2003, DeLeo and his brother Dean joined Filter frontman Richard Patrick and drummer Ray Luzier to form the band Army of Anyone. The group met after Patrick contacted the DeLeos about writing material for Filter's fourth album. The band eventually called in Luzier in for an audition, found the formula worked, and the band was formed. The band's self-titled debut album was released on November 14, 2006. The album became a critical success; some went as far to label the album as one of the best of the year. DeLeo summed up his sound on the album as follows;

Stone Temple Pilots' debut album Core was recorded with a Jazz-type bass prototype version of his Schecter Model-T bass, a G&L L2000, and an Ampeg SVT amplifier with an 8x10 cabinet. Purple, their second album, was recorded with his live rig. DeLeo's usual studio rig for most of Tiny Music... Songs from the Vatican Gift Shop, all of No. 4, and all of Shangri-La-Dee-Da, all by Stone Temple Pilots, was more complicated; he split his signal, bi-amping it to a '67 50-watt Marshall Plexi guitar head with '69 Marshall keyboard 8x10 cabinet, and a '59 Fender Bassman amplifier with a custom 1x15 cabinet. This configuration, which DeLeo noted in a Bass Player Magazine article as being an idea he lifted from Chris Squire of Yes, allowed him to use distorted and clean sounds simultaneously and produce more workable sounds on tape by blending the signals to taste.

During Stone Temple Pilots' hiatus in 1997 due to Weiland's run-ins with the law, DeLeo, his brother Dean, and Kretz joined with singer Dave Coutts of Ten Inch Men and formed Talk Show. Released in 1997 on Atlantic Records, their eponymous debut album peaked at #131 on the Billboard 200 and was considered a commercial flop. Coutts was eventually fired and the band disbanded. Weiland went into rehab and released a solo album during this time.

DeLeo met Scott Weiland (who would eventually become lead singer of Stone Temple Pilots) at a Black Flag concert in Long Beach. They soon realized that they were both dating the same woman. After she moved to Texas, Weiland and DeLeo moved into her San Diego apartment, where they tried to form a band. They eventually hooked up with drummer Eric Kretz, and DeLeo managed to convince his brother Dean to play guitar in their new band. The band took the name Mighty Joe Young. They played many gigs around LA bars, and were eventually signed onto Atlantic Records in 1992. However, the name "Mighty Joe Young" had already been taken, so the band was forced to change their name to "Shirley Temple's Pussy" and then "Stone Temple Pilots" which has no specific meaning, according to Weiland other than that it retained the STP initials.

During their years of greatest success in the 1990s, Stone Temple Pilots came to be one of the most successful bands of the decade. DeLeo is credited with much of the band's music, including the famous intros for the songs "Plush" and "Interstate Love Song". Although sales of their records exceeded over 30 million, the band disbanded due to Weiland's continuous problems with drug abuse.

Robert Emile DeLeo (born February 2, 1966) is an American bass player, songwriter, and backing vocalist for the rock band Stone Temple Pilots. He is part of Delta Deep, and he has also played in Talk Show and Army of Anyone. He is the younger brother of Stone Temple Pilots guitarist Dean DeLeo. He is also the current bass player for the supergroup Hollywood Vampires.

Although he primarily uses the Schecter bass live, for recording purposes he has used a wide variety of basses, and has a fondness for oddball off-brand basses from the 1960s, particularly short-scale hollowbody basses which he strung with flat wound strings. In Army of Anyone's "Goodbye" video, he played a Rickenbacker bass.
