Context paragraphs:
Notorious Lightning &amp; Other Works: Notorious Lightning and Other Works is an EP by Destroyer, released on January 25, 2005 on Merge Records.  After shocking many fans by supporting the synth driven album "Your Blues" with the avant-guitar band Frog Eyes, Dan Bejar decided to put to tape some of the very different versions of songs from "Your Blues".  Similar versions of these songs are currently streaming from CBC Radio Three.

Destroyer (band): Destroyer is a Canadian rock band from Vancouver, British Columbia fronted by singer-songwriter Dan Bejar and formed in 1995.  Destroyer songs are characterized by abstract, poetic lyrics and idiosyncratic vocals.  The band's discography draws on a variety of musical influences, resulting in albums that can sound markedly distinct from one another; in Bejar's words, "That's kind of my goal: to start from scratch every time."

Aleksi Sihvonen: Aleksi Sihvonen is the current vocalist for the Finnish band Medicated.  He replaced Norther's vocalist Petri Lindroos in 2009, until the group disbanded in 2012.  He was also the former guitarist and vocalist of Imperanon.

Dan Bejar: Daniel Bejar ( ; born October 4, 1972) is an independent singer-songwriter from Vancouver, British Columbia, Canada.  Bejar has gained widespread popularity through his musical collaborations with Vancouver indie-rock band The New Pornographers, but has released far more material as the frontman of his band Destroyer.  He is renowned for his poetic and often cryptic lyrics as well as his unorthodox vocals.  In 2006, he joined with Carey Mercer of Frog Eyes and Spencer Krug of Sunset Rubdown and Wolf Parade as part of another indie supergroup, Swan Lake.  He has also collaborated with his girlfriend Sydney Hermant as the duo Hello, Blue Roses, whose debut album was released in 2008.

Petri Lindroos: Petri Lindroos (born 10 January 1980 in Espoo, Finland) is a melodic death/folk metal guitarist and vocalist.  He is currently the lead vocalist in Ensiferum and, prior to this, was a founder and lead vocalist for Norther.

Dragonheads (EP): Dragonheads is an EP by Finnish folk metal band Ensiferum.  It was released on February 15, 2006 by Spinefarm Records.  It is the first Ensiferum release featuring the then recently hired members Petri Lindroos, Sami Hinkka and Janne Parviainen.  Mastered at Finnvox Studios.  "Warrior's Quest" and "White Storm" are the re-recordings of songs from the band's second demo.  "Finnish Medley" is a medley of the Finnish traditional pieces "Karjalan kunnailla", "Myrskyluodon Maija", and "Metsämiehen laulu".

Markus Toivonen: Markus Toivonen (born 1979 in Helsinki) is the founding member of the Finnish folk/death metal band Ensiferum.  Markus founded the band in 1995 and is the sole original member to have lasted the distance to Ensiferum's present incarnation.  His role in the band is guitarist and primary songwriter.  He has always contributed backing vocals and since the departure of Jari Mäenpää in 2004 has taken up a greater role behind the microphone, sharing the clean vocal parts with new bass player Sami Hinkka, with Mäenpää's replacement Petri Lindroos handling the harsh vocals.

Mass Romantic: Mass Romantic is the debut album by Canadian indie rock supergroup The New Pornographers.  Produced by David Carswell and band bassist John Collins, it was released on Mint Records on November 28, 2000.  The album was three years in the making, with musicians A.C. Newman and Dan Bejar writing songs as early as 1998.  With encouragement from peers, they recorded an album with other Canadian musicians from groups including The Evaporators, Zumpano, and Destroyer.

Whiteout Conditions: Whiteout Conditions is the seventh studio album by Canadian indie rock band The New Pornographers.  It was released on April 7, 2017, and is the first album not to feature either longtime drummer Kurt Dahle or singer-songwriter Dan Bejar.

N (album): N is the fifth full-length studio album by Finnish melodic death metal band Norther.  The album was released through Century Media Records on February 13, 2008 for Finland, and other dates in February for other parts of Europe.  The track "Frozen Angel" from their previous EP, "No Way Back", was re-recorded for the album.  "We Rock" and "Frozen Angel" have been made into music videos.  This is also the last Norther album to have founding member Petri Lindroos on vocal and guitar duties.
