Question: What British magazine has featured Peter Hammill from the progressive rock band Van der Graaf Generator?

Context paragraphs:
Present (Van der Graaf Generator album): Present is the ninth studio album by British progressive rock band Van der Graaf Generator, released in 2005.  It was the band's first studio album since "The Quiet Zone/The Pleasure Dome" in 1977, and the first with the 'classic' line-up since "World Record" in 1976.  The Charisma Records label was reactivated for its release, as well as a reissue series of Van der Graaf Generator's back catalog and Peter Hammill's solo releases from 1972-80.

Chameleon in the Shadow of the Night: Chameleon in the Shadow of the Night was the second solo album by British singer-songwriter Peter Hammill.  It followed in the aftermath of the breakup of Hammill's band Van der Graaf Generator, although (as with many of Hammill's "solo" albums from this period) the other members of Van der Graaf Generator all perform on the album, blurring the distinction between solo and group work.

Vital (Van der Graaf Generator album): Vital: Van der Graaf Live is the first live album by English progressive rock band Van der Graaf Generator.  It was recorded 16 January 1978 at the Marquee Club in London and was released in July, one month after the band's 1978 break-up.  The album (on vinyl and, later, on CD) was credited under the abbreviated name Van der Graaf, like the previous year's "The Quiet Zone/The Pleasure Dome" (1977), and featured the same line-up plus newcomer cellist Charles Dickie, who had officially joined the band in August 1977, and original saxophonist and flautist David Jackson, who re-joined the band for this recording.

Peter Hammill: Peter Joseph Andrew Hammill (born 5 November 1948) is an English singer-songwriter.  He is a founding member of the progressive rock band Van der Graaf Generator.  Best known as a singer, he also plays guitar and piano.  He also acts as a record producer for his own recordings and occasionally for other artists.  In 2012, he was recognised with the Visionary award at the first Progressive Music Awards.

The Box (Van der Graaf Generator album): The Box is a four CD box set by Van der Graaf Generator, containing recordings that had been released before, but also BBC-recordings and some live recordings that were never officially released before.  It was released in 2000 by Virgin Records.  Included in the sleeve notes are introductions by Guy Evans and Tony Banks from Genesis, a timeline of Van der Graaf Generator events from 1967 to 1978 (including a list of dates and places for every then-known concert by the band), an essay about the organs by Hugh Banton, an essay about Van der Graaf Generator compositions by Peter Hammill, an essay about saxophones by David Jackson and an essay about being a Van der Graaf Generator-aficionado by Ian Laycock.

The Union Chapel Concert: The Union Chapel Concert is a live album by Guy Evans and Peter Hammill, recorded in the Union Chapel in London, 3 November 1996, and released as a double CD in March 1997.  The album is noteworthy because it is the first time the four ex-members of Van der Graaf Generator, Hammill, Evans, Hugh Banton and David Jackson, played together in front of a paying audience since the band had broken up in 1978.  The subtitle on the front of the album reads: "featuring a one song, one-off reformation of Van der Graaf Generator."  David Jackson and Hugh Banton were unannounced guests and played a Soundbeam-medley and a Samuel Barber Adagio for strings on the church organ respectively.  All songs that evening were played in varying line-ups.  Only "Lemmings" was played by Hammill, Evans, Banton and Jackson.

Prog (magazine): Prog is a British magazine dedicated to progressive rock music.  The magazine, which is edited by Jerry Ewing, was launched in March 2009 as a spin-off from "Classic Rock" and covers both past and present artists.

Fool's Mate (album): Fool's Mate is the debut solo album by Peter Hammill of progressive rock band Van der Graaf Generator.  The title is both a chess and tarot reference.  It was produced by Trident Studios' in-house producer John Anthony.  The album was recorded in 1971, in the midst of one of Van der Graaf Generator's most prolific periods.  Hammill used the album to record a backlog of songs which were much shorter and simpler than his Van der Graaf Generator material, and declared on the original album sleeve: "This isn't intended to be any kind of statement of my present musical position, but at the same time, it is an album which involves a great deal of me, the person, basically a return to the roots."

Peter Hammill discography: This is the discography of Peter Hammill, English singer-songwriter, and a founding member of progressive rock band Van der Graaf Generator.  For albums released by Van der Graaf Generator, see Van der Graaf Generator discography.

The Silent Corner and the Empty Stage: The Silent Corner and the Empty Stage is the third album by British singer-songwriter Peter Hammill.  It was released on Charisma Records in 1974, during a hiatus in the activities of Hammill's progressive rock band Van der Graaf Generator.  However, like many of Hammill's albums of this period, all the members of Van der Graaf Generator perform on the recording, blurring the distinction between solo and group work.
