[1] The album was produced by drummer Mike Portnoy and keyboardist Derek Sherinian under the name "The Del Fuvio Brothers" a nickname they adopted during their time together in Dream Theater.

[2] The album was released as CD, digital download, vinyl and a special edition containing a bonus disc with instrumental versions of the songs and an alternate mix of "Opus Maximus.

[8][12] When Portnoy and Sherinian started the band they thought it would go in a direction similar to Dream Theater only to realize it would end up completely different.

[13] Psychotic Symphony is influenced by: Deep Purple ("Divine Addiction"), Van Halen ("Coming Home") and U.K.

Bumblefoot, Sherinian, and Portnoy began work initially with Sheehan and Soto joining the band halfway into the recording sessions due to touring commitments.

According to Portnoy: "'Coming Home' feels like the Sons of Apollo Grand Entrance--almost like a fighter entering the ring.

[18] "Labyrinth" is Portnoy's personal favorite on the album and features unusual time signatures and orchestrations.

"[7] The song was the subject of a promotional video directed by Vicente Cordero and released simultaneously with the album.

[19] "Figaro's Whore" is a short keyboard instrumental track that serves as a prelude to "Divine Addiction" and was compared by Portnoy to Van Halen's "Eruption."

The musicians are as good as you'd expect, especially Portnoy, who almost seems to drag the rest of the band along with him, and Thal, whose playing veers from ugly metallic crunch to stunningly fluid solo.. (the album is) fierce, loud, bewildering, brilliantly performed and monstrously entertaining".

[21] In a less favorable review for Metal Injection, Jordan Blum felt the album was competent overall but lacked originality.

He said the album was "filled with in-your-face intricacy, uninspired lyricism, and raucous vocals, [...] packed with impressive performances from start to finish, as well as a few standout moments; however, it also fails to go beyond mere sufficiency in every respect, resulting in a forgettable effort that’s lazily innocuous and overwhelmingly familiar.
