[5] In 1971, Bobby Liebling and Geof O'Keefe left their previous groups (Shades of Darkness and Space Meat, respectively) to form a new band that reflected their interest in the emerging genres of metal and heavy rock.

Although the band changed its name several times between 1972 and 1974 ("Macabre" in 1972, "Virgin Death" in 1973, and "Wicked Angel" in 1974 were all considered during this period), they eventually (and permanently) returned to Pentagram.

[6] During their five-year career, they were represented by seven different managers, including Gordon Fletcher, a Washington, D.C. rock journalist, Steve Lorber, Phillip Knudsen, Skip Groff, Bob Fowler, Tim Kidwell, and Tom McGuire.

After a month of rehearsals, Space Meat alumnus John Jennings joined to create Pentagram's dual-guitar "Mark II" line-up, but he was soon asked to leave the group and his position was filled by guitarist O'Keefe.

McAllister would leave for California in 1980 to attend classes at the Guitar Institute of Technology, and Jennings would subsequently collaborate with Mary Chapin Carpenter during the 1980s and into the 1990s as her primary guitarist.

On Christmas Day 1971, this Pentagram line-up began rehearsing, with Liebling on vocals, McAllister on guitar, Greg Mayne (formerly of Space Meat) on bass, and O'Keefe on drums.

[10] In 1980, bassist Lee Abney and guitarist Victor Griffin formed a Knoxville, Tennessee, (later based in Northern Virginia) doom metal band named Death Row.

In 1985, the band released their first studio album, featuring "Death Row" material and the line-up of Liebling on vocals, Griffin on guitar, Swaney on bass, and Rose on drums.

Pentagram split up again, and in 1996, a new line-up was forged,[12] consisting of Liebling on vocals, Hasselvander on drums,[13] and new members Greg Reeder on guitar and Ned Meloni on bass.

Shortly afterward, Pentagram re-emerged as a studio duo, with Liebling retaining vocal duties and Hasselvander taking care of all instrumentation.

The combo of Liebling and Hasselvander occasionally performed live as Pentagram during this period, assisted by bassist Walter White and drummer Dale Russell.

Shortly after Sub-Basement, Hasselvander split with Liebling, who soon recruited guitarist Kelly Carmichael, bassist Adam Heinzmann, and drummer Mike Smail, all members of the doom metal band Internal Void.

Place of Skulls briefly featured doom metal legend Scott "Wino" Weinrich on their 2003 With Vision album, though he later left to concentrate on the Hidden Hand.

On September 15, 2006, Liebling joined Witchcraft onstage at a show at The Rock and Roll Hotel in Washington D.C., to sing Pentagram covers "When the Screams Come" and "Yes I Do".

For live performances, Hasselvander recruited Kayt Vigil on bass and former Pentagram drummer and Maryland doom mainstay Isom on drums.

On August 23, 2008, a new Pentagram line-up was announced by Liebling, which featured guitarist Russ Strahan, former live drummer Gary Isom, and bassist Mark Ammen, who came in after a short period with Kayt Vigil.

The band later embarked on a seven-date mini-tour, which included two sold-out shows in Chicago plus dates in Seattle, Portland, Austin, San Francisco, and West Hollywood.

In February 2011, Metal Blade Records announced that Pentagram would play South by Southwest in March 2011, followed by a European tour beginning on April 14, 2011, at the Roadburn Festival in the Netherlands.

[20] Pentagram played several shows in the U.S. and toured Europe during 2012 and 2013, including dates in the UK, Germany, Norway, Switzerland, Sweden, Austria, France, Slovenia, Greece, Italy, and Spain.

[21] Upon Griffin's return, Pentagram embarked on a U.S. West Coast tour in February 2014, covering Seattle, Portland, San Francisco, Las Vegas, Albuquerque, Denver, Salt Lake City, and Los Angeles.

In February 2015, new drummer Pete "Minnesota" Campbell, previously in Griffin's In-Graved, was announced, as was a new album titled Curious Volume, which was released on August 21.

[23] In October of that year, Liebling pleaded guilty to "abuse and neglect of a vulnerable adult custodian", and was sentenced to 18 months at the Montgomery County Detention Center.

[24] Pentagram resurfaced in January 2019, announcing the return of vocalist Bobby Liebling and guitarist Matt Goldsborough in place of Victor Griffin.

[27] In June 2024 the new incarnation of the band was revealed; along with Liebling, Mos Generator musicians Tony Reed and Scooter Haslip (guitars and bass, respectively), and drummer Henry Vazquez of Saint Vitus, the Skull, Spirit Caravan and Sourvein.

[32] After Palmer's departure from Pentagram, Bedemon reformed in 1979 to record three more songs: "Time Bomb", "Nighttime Killer", and an unnamed composition by O'Keefe.
