Keep Telling Myself It's Alright is the debut studio album by American rock band Ashes Divide, the solo-project by A Perfect Circle guitarist Billy Howerdel.
 While efforts towards a Howerdel solo album were started even back in his time in A Perfect Circle during touring in support of their 2003 album "Thirteenth Step", commitments to A Perfect Circle and other projects, along with some difficult recording sessions, pushed the album's release out to April 8, 2008.
 Its first single, "The Stone," entered radio circulation in January of that year.
Ashes Divide is the name used for the solo project of American rock musician Billy Howerdel, guitarist of the alternative rock band A Perfect Circle, where he is the primary songwriter, musician, producer, and vocalist.
 The project's debut album, "Keep Telling Myself It's Alright", was released in 2008.
 Howerdel formed a live band and toured in support of the album through the rest of the year, but the project fell to the wayside after A Perfect Circle reformed and toured in 2010 and 2011.
 Howerdel would work on both projects for a while until late 2012, where he announced his primary focus is completing the second album, of which he hoped to enter the mixing phase in January or February 2013.
A Perfect Circle Live: Featuring Stone and Echo is a live box set by American rock supergroup, A Perfect Circle.
 It was released via the band's own label, A Perfect Circle Entertainment, on November 26, 2013, a week after the release of the band's greatest hits album, "Three Sixty".
genre b.goode is the record label used by Australian band TISM.
 Formed around 1995, the unusual title comes from one of the founding members of TISM who chose his stage name as "Genre B. Goode".
 According to the remaining members of TISM, Genre's "complete non-sell-out stance" was "simultaneously stupid and inspiring to the rest of the band" which is why they named their record label after him.
 The label, however, is not a label in and of itself.
 It tends to be used as a vanity label the band attach to their recordings regardless of who they're signed to at the time.
TISM (an acronym of This Is Serious Mum) were a seven-piece anonymous alternative rock band from Melbourne, Australia.
 The group were formed on 30 December 1982 by vocalist/drummer Humphrey B. Flaubert, bassist/vocalist Jock Cheese and keyboardist/vocalist Eugene de la Hot Croix Bun, and enjoyed a large underground/independent following.
 Their third album, "Machiavelli and the Four Seasons", reached the Australian national top 10 in 1995.
The discography of American alternative rock supergroup A Perfect Circle consists of three studio albums, two compilation albums, one extended play, one video album, nine singles, one promotional single and ten music videos.
 A Perfect Circle is the brainchild of Billy Howerdel.
 After hearing demos of Howerdel's music, Maynard James Keenan, the lead singer of Tool, offered his services as vocalist.
 Howerdel agreed, and the band formed in 1999.
 They were then joined by bassist/violinist Paz Lenchantin, guitarist Troy Van Leeuwen, formerly of Failure, and drummer Tim Alexander, formerly of Primus.
 Soon after entering the studio to record their first album, Alexander was replaced by Josh Freese of The Vandals. "
Mer de Noms" was released in May 2000, selling 188,000 copies its debut week.
 The band embarked on a number of headlining tours all over the world to promote the album which was certified gold by the Recording Industry Association of America (RIAA) one month after its release, and platinum just four months later.
The Beasts of Suburban is a 1992 EP by anonymous Australian band TISM.
 The title is pun on the name of another Australian band, Beasts of Bourbon.
 TISM's producer for this album, Tony Cohen, previously worked with that group.
 At the ARIA Music Awards of 1993, he was nominated for Producer of the Year for the track, "Get Thee to a Nunnery".
 This is the first TISM release to feature Tokin' Blackman on guitar, having replaced Leek Van Vlalen.
 The track, "Morningtown Ride", was listed as one of the 10 Greatest Songs About Melbourne by ToneDeaf's Corey Tonkin.
A Perfect Circle is an American rock supergroup formed in 1999 by guitarist Billy Howerdel and Tool vocalist Maynard James Keenan.
 A Perfect Circle has released three albums: their debut "Mer de Noms" in 2000, a follow up, "Thirteenth Step" in 2003, and an album of radically re-worked cover songs titled "Emotive" in 2004.
 Shortly after "Emotive"' s release, the band went into hiatus while Keenan returned to Tool and starting up solo work in the form of the band Puscifer, and Howerdel releasing a solo album, "Keep Telling Myself It's Alright", under the moniker Ashes Divide.
 Band activity was sporadic in the coming years; the band reformed in 2010, and played live shows on and off between 2010 and 2013, but fell into inactivity after the release of their greatest hits album, "Three Sixty", and a live album box set, "" in late 2013.
 However, in 2017, the band returned to touring and announced plans to record and release a fourth studio album under a new record label, BMG Rights Management, between late 2017 and early 2018.
The Miami Circle, also known as The Miami River Circle, Brickell Point, or The Miami Circle at Brickell Point Site, is an archaeological site in Downtown Miami, Florida.
 It consists of a perfect circle measuring 38 feet (11.5m) of 600 postmolds that contain 24 holes or basins cut into the limestone bedrock, on a coastal spit of land, surrounded by a large number of other 'minor' holes.
 It is the only known evidence of a prehistoric permanent structure cut into the bedrock in the Eastern United States, and considerably predates other known permanent settlements on the East Coast.
 It is believed to have been the location of a structure, built by the Tequesta (also Tekesta) Indians, in what was possibly their capital.
 Discovered in 1998, the site is believed to be somewhere between 1,700 and 2,000 years old.
 Some scholars have questioned both its age and its authenticity.
Passive is a song from the 2004 album "eMOTIVe" by A Perfect Circle.
 It is a remake of the song "Vacant" by the now-defunct band Tapeworm.
"Vacant" was notably first performed by A Perfect Circle without Trent Reznor's agreement.
