Universe is the first studio album by instrumental rock/progressive metal supergroup Planet X, released on June 6, 2000 through Inside Out Music.
 The album is essentially a continuation of keyboardist Derek Sherinian's 1999 debut solo release "Planet X", but this time as a full band effort featuring guitarist Tony MacAlpine and drummer Virgil Donati.
Sean Aaberg was born in Oakland, California.
 He is the son of Philip Aaberg and LouAnn Lucke.
 He grew up in Oakland, attending Bishop O'Dowd High School and briefly attended the California College of the Arts.
 As a kid, he liked "anything weird, nasty and old", including cheap magazines and bought thousands of them, he said in an interview.
 He and his friends read "Mad", drew comics, liked to listen to Cheech and Chong and the Ramones on the Dr. Demento show, and later discovered the Church of the Subgenius.
 He admired the movies of Ralph Bakshi.
 The interviewer noted that Aaberg writes in ALL CAPS.
 Sean founded and played drums in the Oakland-based Hardcore Punk band The Masked Men, played drums for Baltimore-based Anarcho Punk band A//Political and founded and played drums for Eugene-based Rock and Roll band The Latrines.
The Rosebuds are an indie rock band from Raleigh, North Carolina, United States.

Planet Us (pronounced "Planet-uss") was a short-lived supergroup that formed in 2002 with Sammy Hagar on lead vocals, Neal Schon on guitar, Michael Anthony on bass, and Deen Castronovo on drums.
 The band later recruited a fifth member - famed guitarist Joe Satriani - when their original choice, Slash, turned them down.
The Rats were an American garage punk band from Portland, Oregon, formed by Fred Cole previously of the garage rock band, The Lollipop Shoppe.
 Cole played guitar and sang, his wife, "Toody" played bass and sang, and initially Rod Rat played drums.
 Their sound was a raw mix of punk rock with occasional country touches.
 Their self-titled debut album appeared on Cole's Whizeagle label in 1980.
 Soon after, Rod Rat left the band, though he guested on the 1981 follow-up "Intermittent Signals" before his death by suicide.
 (Prior to his suicide Rod Rat (aka Rod Hibbert) also played drums in 1980-81 for Portland power pop band Domino Theory).
 Sam Henry, formerly of the Wipers, played drums on this LP but left to join another Portland band, Napalm Beach.
 Louis Samora was on the drum throne for the 1983 album "In a Desperate Red", still on Whizeagle.
 Samora left in 1984 to concentrate on his rockabilly band, The Jackals.
 The band broke up, but Bill Barker of Profile Studios in Vancouver, British Columbia convinced the band to reunite for a single.
 It appeared under the band name The Desperate Edge later in 1984.
 Soon after, Cole assembled a country band, Western Front, and he and Toody later reunited in Dead Moon.
 The Rats' records have long been out of print and sell for high prices on eBay.
 In 2008, Portland's Mississippi Records reissued the first album on vinyl.
Quantum is the third studio album by instrumental rock/progressive metal supergroup Planet X, released in 2007 through Inside Out Music.
