"Trisector" is the tenth studio album by the English Progressive rock band, Van Der Graaf Generator. Released on 17th March 2008, the album marks the band's return as a trio, comprising Peter Hammill, Guy Evans, and Hugh Banton, following the departure of David Jackson, the band's saxophonist. "Trisector" was recorded and mixed at the Gaia Studio in Dorset, England.
The album features ten tracks with a duration of 59 minutes. It can be characterised by the usual complex song structures, the typical Hammill's lyrical visions, alongside the classic, strong organ sounds from Hugh Banton. The first track, "The Hurlyburly," is an instrumental one, and probably the most thrilling opening of a Van Der Graaf Generator album. Another notable track, "Interference Patterns" is recognisably Van Der Graaf Generator, featuring intensive organ work and expressively splintered lyrics. The album ends on the solemn note of "Lifetime," an introspective song dealing with the passing of time.
Critically, the album was well-received and is noted for maintaining the intensity of their earlier works despite their reduction to a three-piece band. Musically, Trisector leans heavily on Hammill's vocals and lyrics, showcasing their matured and more introspective side. While the absence of Jackson’s sax and flute was felt, the band successfully managed to fill the sonic space with Banton’s organ and Hammill’s guitar work.
In sum, "Trisector" is a notable work in Van Der Graaf Generator's discography, which sees the band reconfiguring and exploring new directions while still respecting its musical heritage. It encapsulates the band's ability to create fresh and engaging music despite having been active for over four decades.
