Question: Which vocalist has worked under more band names, Jus Oborn or James Dewar?

Context paragraphs:
Pre-Electric Wizard 1989–1994: Pre-Electric Wizard 1989–1994 is a compilation of songs featuring Electric Wizard frontman Jus Oborn with his previous band, which changed its name twice.

Witchcult Today: Witchcult Today is the sixth studio album by English doom metal band Electric Wizard.  It was recorded entirely on vintage 1970s equipment at Toe Rag Studios and was released in November 2007.  The sound of "Witchcult Today" was less harsh than preceding albums and Jus Oborn's vocals are much more prominent.  It was the band's most well-received album in seven years.

Sub Templum: "Sub Templum" is an album by British doom metal band Moss.  Released in 2008, it is their first for Rise Above Records (owned by former Napalm Death and Cathedral vocalist Lee Dorrian) and second overall.  It was produced by Electric Wizard guitarist/vocalist Jus Oborn, and it features 4 songs, two of which are over 20 minutes in length (with the longest, "Gate III" being 35:31).

Come My Fanatics…: Come My Fanatics… is the second studio album by English band Electric Wizard.  The album was released in January 1997 on Rise Above Records and was produced by Rolf Startin, Mike Hurst and band member Jus Oborn.  It was the group's follow-up to their eponymous album "Electric Wizard".  Oborn described the release as a reaction to the sound on the album, which he had felt was not as heavy as he wanted the group to sound.  The sound developed on the record was described by Lee Dorian as breaking the traditional doom metal sound with an unpolished approach.

James Dewar (musician): James Dewar (12 October 1942 – 16 May 2002) was a Scottish musician best known as the bassist and vocalist for Robin Trower and Stone the Crows, the latter having its beginnings as the resident band at Burns Howff in Glasgow.

Dewar benzene: Dewar benzene or bicyclo[2.2.0]hexa-2,5-diene is a bicyclic isomer of benzene with the molecular formula CH.  The compound is named after James Dewar who included this structure in a list of possible CH structures in 1867.  However, he did not propose it as the structure of benzene, and in fact he supported the correct structure previously proposed by August Kekulé in 1865.

Vacuum flask: A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings.  Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck.  The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection.

Jus Oborn: Justin "Jus" Oborn is the lead vocalist, guitarist and lyricist of Electric Wizard, an English doom metal band from Dorset.  Prior to forming Electric Wizard, Oborn was a member of the band Lord of Putrefaction, which changed its name to Thy Grief Eternal and then to Eternal.

Cryogenic storage dewar: A cryogenic storage dewar (named after James Dewar) is a specialised type of vacuum flask used for storing cryogens (such as liquid nitrogen or liquid helium), whose boiling points are much lower than room temperature.  Cryogenic storage dewars may take several different forms including open buckets, flasks with loose-fitting stoppers and self-pressurising tanks.  All dewars have walls constructed from two or more layers, with a high vacuum maintained between the layers.  This provides very good thermal insulation between the interior and exterior of the dewar, which reduces the rate at which the contents boil away.  Precautions are taken in the design of dewars to safely manage the gas which is released as the liquid slowly boils.  The simplest dewars allow the gas to escape either through an open top or past a loose-fitting stopper to prevent the risk of explosion.  More sophisticated dewars trap the gas above the liquid, and hold it at high pressure.  This increases the boiling point of the liquid, allowing it to be stored for extended periods.  Excessive vapour pressure is released automatically through safety valves.  The method of decanting liquid from a dewar depends upon its design.  Simple dewars may be tilted, to pour liquid from the neck.  Self-pressurising designs use the gas pressure in the top of the dewar to force the liquid upward through a pipe leading to the neck.

Mount Dewar: Mount Dewar ( ) is a mountain rising to about 1,600 m to the southwest of Aronson Corner in the Pioneers Escarpment, Shackleton Range.  It was photographed from the air by the U.S. Navy in 1967 and surveyed by the British Antarctic Survey from 1968–71.  In association with the names of pioneers of polar life and travel grouped in this area, it was named in 1971 by the UK Antarctic Place-Names Committee after Sir James Dewar, a Scottish chemist and physicist who invented the thermos flask about 1892.
