"Drifting" is a song by contemporary Christian musician Plumb featuring Jars of Clay frontman Dan Haseltine from her forthcoming sixth studio album, "Need You Now".
 It was released on August 30, 2011, as the first single from the album.
"Crazy Times" is a song recorded and performed by Jars of Clay.
 The song was a writing collaboration between the band members Dan Haseltine and Stephen Mason with songwriters Mark Hudson and Greg Wells.
 It was the first single from their second studio album, "Much Afraid".
 The single fared well in the mainstream, peaking at No. 38 on the "Billboard" Modern Rock Tracks chart.
 The demo version of the song can be found on the album "The White Elephant Sessions", while a live version of the song is included on the 2003 double album, "".
 This song also appears on the "WOW 1999" compilation album.
Gray Matters is an imprint record label structured underneath the Nettwerk Music Group.
 The label was founded in 2007 by Jars of Clay band members Dan Haseltine, Stephen Mason, Matt Odmark, and Charlie Lowell.
 The creation of the label was in response to the band's record contract's ending with Essential Records, and the band's desiring to control their music output.
 The label will be distributed by Provident/Integrity Distribution (as was Essential Records) to the Christian and mainstream markets.
 The band had been with Nettwerk under their management division since 2003.
Marzuki was an indie folk rock band from Holland, MI, with a significant fan base in western Michigan in the mid to late 1990s.
 They were especially popular among Hope College, Calvin College, and Grand Valley State University students.
 Marzuki's members included Shannon Stephens on vocals and guitar, Jamie Kempkers on cello, Matthew Haseltine (brother of Jars of Clay's Dan Haseltine) on guitar and bass, and Sufjan Stevens on guitar, percussion, and the more exotic instruments (especially the recorder).
 Their lyrics often explored spiritual or romantic themes.
Daniel Paul "Dan" Haseltine (born January 12, 1973) is an American singer best known as lead vocalist for Christian alternative folk rock group Jars of Clay.
 Haseltine has performed vocals, piano, accordion, percussion and most recently, melodica, while with Jars of Clay.
 He has had different artistic titles, including songwriter, producer, film composer, music supervisor and art designer.
"Hand" is a song recorded and performed by Jars of Clay.
 It is the fifth of six radio singles from the band's 1999 studio album, "If I Left the Zoo".
 The single was sent only to Christian adult contemporary radio stations.
 The song was a writing collaboration between the band's Dan Haseltine and Stephen Mason along with singer-songwriter Jonathan Noël.
 A different recording of the song appears on Jonathan Noël's album, "Hand", with Charlie Lowell lending help on keyboards while Stephen provides guitar work.
Honey was a Christian, ambient rock band composed of Doug Moss, Paul Lagestee, Billy Wan, and Roger Moss.
 The band recorded three albums between 1997 and 2001.
 The first two, "Lovely" and "Lost on You", were released on the now-defunct Sub•Lime Records.
 Their third album, aptly titled "Three", was released by Northern Records.
 The first effort was produced by Christian alt/rock legend Steve Hindalong and was characterised by a rough, guitar-driven sound.
 For their second effort, production credits were diverse but significant with Jars of Clay's Dan Haseltine and Stephen Mason lending a hand as well as The Prayer Chain alumni Eric Campuzano and Wayne Everett.
 The result was a more approachable sound that was at once extraordinarily mellow and enormously engaging.
 As a departure from their first album, the work could be described as a "concept worship album".
 Indeed, many songs read as abstract praises of God.
 With their third album, Honey made a strong musical departure, moving to an up-tempo, alt/pop flavour.
 Thematically, the focus moved from theology to what could be described as "a soundtrack to a wistful, longing, romantic love life".
 After "Three", Honey disappeared from the music scene, although Doug Moss is rumoured to play with the anonymous band Cush.
Need You Now is the sixth studio album by American singer-songwriter Plumb released on February 26, 2013.

 A deluxe edition of the album was released on September 16, 2014 with six additional tracks.
Ryan McCombs (born July 16, 1974) is an American vocalist.
 From 1997 to 2004 he was the vocalist of the rock band Soil.
 McCombs has also served as the vocalist for alternative metal band Drowning Pool from 2005 until his departure in 2011.
 He has since reunited with Soil.
Indelible Grace is an artist collective based in Nashville, Tennessee, that has led a movement to restore the historic practice of writing new melodies to old hymn texts.
 The community of songwriters and musicians grew out of the Reformed University Fellowship at Belmont University, led by RUF campus minister Kevin Twit.
 Their first album was simply titled "Indelible Grace", taken from a line in the Augustus Toplady hymn "A Debtor to Mercy Alone."
 They have also made all of the sheet music available online for free through the Indelible Grace Hymnbook.
 Key artists involved in the projects include Sandra McCracken, Matthew Smith, Emily Deloach, and Jeremy Casella.
 Other notable artists that have been featured on recordings include Derek Webb, Andrew Osenga (from The Normals), Matthew Perryman Jones, and Dan Haseltine (from Jars of Clay).
