released on DVD as "InstruMENTAL Inspiration". They toured Europe and Asia concluding with a live DVD/CD "Live in Tokyo" released on September 24, 2013. In 2014, PSMS performed two songs at the TAMA 40th Anniversary Party at NAMM January 25, and also the Progressive Nation at Sea cruise on the Norwegian Pearl February 18–22, co-promoted by Sherinian and Portnoy. Solo career Since 1999, Sherinian has recorded eight solo albums, featuring performances by numerous highly acclaimed musicians. Sherinian's first solo album, Planet X (1999), written and recorded with Australian drummer Virgil Donati, led to the formation of a band of the same name (Planet X). Guitar virtuoso Tony MacAlpine was recruited to complete the band. Sherinian has stated that his intention when forming Planet X was to create a group of musicians that "played their instruments so fiercely that they would strike fear in the hearts of all musicians". In 2017, the short documentary "Return to Planet X" reflecting on the making of this album. In 2001, Sherinian teamed with drummer Simon Phillips and guitarists Steve Lukather and Zakk Wylde to record Inertia, followed by Black Utopia (2003). For Black Utopia, three new faces joined Sherinian's group: bassist Billy Sheehan, rock guitarist Yngwie Malmsteen, and jazz fusion guitarist Al Di Meola. With respect to this fusion-influenced lineup, Sherinian stated: Sherinian also called the album "a lot darker and heavier than [Inertia]". Sherinian extended further into the fusion realm by collaborating with guitarist Allan Holdsworth and violinist Jerry Goodman (formerly of the Mahavishnu Orchestra) on Mythology (2004). In addition to another appearance by Phillips, other musicians appearing on this recording were Zakk Wylde, John Sykes, Steve Stevens, and Tony Franklin. Holdsworth said of the session, "When Derek was finishing his album, he told me he’d love for me to play a guitar solo on it, so I did. I recorded a solo for him in the specific length that he requested, and he put it on that track [which also features Zakk Wylde]. People have told me they really like that guitar solo, but I haven’t heard it in years so I don’t remember it. [laughs]" Since 2002, Sherinian has toured with several well-known artists, including Billy Idol and Yngwie Malmsteen. Derek's fifth solo album, Blood of the Snake (2006), features contributions from Idol, as well as Guns N' Roses guitarist Slash, John Petrucci of Dream Theater, and Brian Tichy; Phillips, Franklin
