Schlarb pushed Psychic Temple's pop influences further to the forefront with PT's second album, Psychic Temple II, which included guest appearances from Sufjan Stevens, Sarah Negahdari of Silversun Pickups, and progressive metal guitarist Paul Masvidal. Released in 2013, the album found Schlarb and his ensemble covering classic tunes by Brian Wilson, Joe Jackson, and Frank Zappa, as well as a handful of Schlarb originals. In 2016, Schlarb returned with the third and most ambitious Psychic Temple album, Psychic Temple III. Recorded at Schlarb's own studio in California and at Fame Studios in Muscle Shoals, Alabama, III was steeped in country and soul influences as well as pop and jazz. The set included performances by Spooner Oldham, David Hood, Avi Buffalo, and Dave Easley. Also appearing in 2016 were Psychic Temple Plays Music for Airports, featuring an interpretation of the groundbreaking Brian Eno piece of the same name, and the 7" single Two Songs About Cults, which included a cover of Tears for Fears' "Everybody Wants to Rule the World." Both of these releases appeared on Joyful Noise, which also issued Psychic Temple IV in 2017. In September 2020, Schlarb issued a unique Psychic Temple project, Houses of the Holy. Conceived as a two-LP vinyl album, Schlarb set out to do something he believed had never been done before: release a two-record set with no unnecessary songs as filler. With this in mind, each of the four sides was recorded in tandem with a different band. His collaborators for Houses of the Holy were Cherry Glazerr, the Chicago Underground Trio, the Dream Syndicate, and a full orchestra accompanying poet Xololanxinxo. ~ Mark Deming, Rovi
