Context paragraphs:
Dead Winter Dead: Dead Winter Dead is the ninth studio album by Savatage, released in 1995.  It is a concept album, dealing with a Serb boy and a Muslim girl who fall in love.  The story of the album also focused on the Bosnian War, which was ongoing at the time.

Hibernus Mortis: Hibernus Mortis was a band started in December 1995 by Cesar Placeres and Ralf Varela.  The band took its name from the ancient Latin translation for "Dead Winter".  Starting out, the South Florida band's primary goal was to create some of the most crushing and extreme music ever recorded.  Taking influence from a variety of sources, musically the band took inspiration from the old-school death metal bands like Incantation, Autopsy, Morbid Angel, Death, Dismember, Immolation, Entombed, Obituary, Vader and Suffocation just to name a few.

Poets and Madmen: Poets and Madmen is the eleventh studio album by the heavy metal band Savatage, released in 2001.  It was their last album before their 12-year hiatus, which lasted from 2002 to 2014.  The album has a loose concept inspired by the career and death of journalist Kevin Carter, but has much less narrative in the lyrics than the previous two rock operas ("Dead Winter Dead" and "The Wake of Magellan") penned by Paul O'Neill.  Everything said in the album is fiction, except with regards to what is sung about Carter.  The album is also noted as it is the only Savatage album to not feature a title song from the album, although the title was taken from lyrics to the track "Symmetry" from the band's 1994 album, "Handful of Rain".

Infamous Stringdusters: The Infamous Stringdusters are an acoustic/bluegrass band.  The band emerged in 2007 with the album "Fork in the Road" on Sugar Hill Records.  The band's current line-up features Andy Hall (Dobro), Andy Falco (guitar), Chris Pandolfi (banjo), Jeremy Garrett (fiddle), and Travis Book (double bass).  The band has become known for a complex, distinctive, and groove-friendly sound along with a bluegrass theme.

Christmas Eve/Sarajevo 12/24: "Christmas Eve/Sarajevo 12/24" is an instrumental medley of "God Rest Ye Merry Gentlemen" and "Carol of the Bells" first released on the Savatage album "Dead Winter Dead" in 1995 as "Christmas Eve (Sarajevo 12/24)."  It was re-released by the Trans-Siberian Orchestra, a side project of several Savatage members, on TSO's 1996 debut album "Christmas Eve and Other Stories".  The piece describes a lone cello player playing a forgotten Christmas carol in war-torn Sarajevo.

Freedom From: Freedom From is a record label based in Minneapolis, Minnesota, which primarily focuses on the international noise underground genre.  The label was founded in 1996 with its first official release by a San Francisco three-piece named Job.  Up until early 1998, the labels focus was singularly cassettes, with the most well-known being the infamous Thurston Moore/Beck/Tom Surgal cassette.  During the course of its primary existence, FF often released either the first or first widely available release by many bands, including Jason Lescalleet, Hair Police, Sightings, No Doctors, Milovan Srdenovic, Violent Ramp, Reynols and many more.  Freedom From was also one of the first entities to book and promote shows nationally for experimental/weird bands from 2001-2004, including the first major tours for bands like Wolf Eyes, Sightings, No Doctors, Hair Police, Mammal, Nautical Almanac and more.  Freedom From also helped bring to prominence the last years of the infamous Church venue in Minneapolis, bringing bands like Animal Collective, Coachwhips, Wolf Eyes, Numbers, 25 Suaves, Glass Candy, Chromatics and many more for their first ever shows in the Twin Cities area.  Finally, Freedom From is also known for the De Stijl/Freedom From and End Times Festivals, bringing in artists like Tony Conrad, The Boredoms, XBXRX, NNCK, Gang Gang Dance, Zip Code Rapists, Borbetomags, Smegma, Burning Star Core, Devendra Banhart, Arthur Doyle and many more.

Jam band: Jam bands are musical groups whose live albums and concerts relate to a unique fan culture that began in the 1960s with the Grateful Dead, and continued with The Allman Brothers Band, which had lengthy jams at concerts.  The performances of these bands typically feature extended musical improvisation ("jams") over rhythmic grooves and chord patterns, and long sets of music that can often cross genre boundaries.  The Grateful Dead continued to grow their fanbase in the second half of the 1980s.  In the mid-1980s the bands Phish, Edie Brickell & New Bohemians, Blues Traveler, Ozric Tentacles, Widespread Panic, Bela Fleck and the Flecktones, Spin Doctors, Col Bruce Hampton and Aquarium Rescue Unit, began touring with Jam band-style concerts.  In the early 1990s and 2000s, a new generation of bands was spurred on by the Grateful Dead's touring and the increased exposure of The Black Crowes, My Morning Jacket, Dave Matthews Band, Widespread Panic and Aquarium Rescue Unit.

Dead Winter Carpenters: Dead Winter Carpenters is a five-piece Alt-Country band from North Lake Tahoe, California, whose music has been described as an Americana blend of progressive bluegrass, roots rock, and folk with an influence from the Bakersfield Sound.
