Question: which artist appeared on Nanci Griffith's third album ?
Context: Mark O'Connor (born August 5, 1961, Seattle) is an American bluegrass, jazz and country violinist, fiddler, composer and music teacher.  O'Connor has received numerous awards for both his playing and his composition. Poet in My Window is singer-songwriter Nanci Griffith's second album.  This album is in the folk music style preceding her next two albums that are more in the country music genre.  A later release of the album included a bonus track, "Can't Love Wrong," in the unusual position as the album's lead-off track, preceding all of the original tracks.  Griffith wrote all but one of the album's tunes. Once in a Very Blue Moon is singer-songwriter Nanci Griffith's third album.  The sounds have become a little more country and a little less folk than her previous albums.  Her first two albums were backed sparsely with instrumentation, but starting with this album, the whole complement of country-styled instrumentalists can be heard.  Noted country musicians performing on the album include banjo player Béla Fleck and champion fiddle player Mark O'Connor.  The title song was covered by Dolly Parton, who included her version on her "Real Love" album in 1985. Storms is singer-songwriter Nanci Griffith's eighth album.  In it she heads in a third musical direction, that of pop music.  Griffith, whose background is primarily folk music, turned toward country music in her preceding four or five albums, and here, again, ventures into a little different style.  Griffith enlisted the talents of noted rock music producer Glyn Johns for the musical style change.  The album landed at #42 on the Billboard Country Albums chart, and at #99 on the Pop Albums chart in 1989. The Dust Bowl Symphony is an album released by Nanci Griffith in 1999.  It consists of songs Griffith had previously released on other albums, but re-recorded with an orchestral backing.  The album was recorded at Abbey Road Studios with the London Symphony Orchestra.  Darius Rucker duets with Griffith on "Love at The Five and Dime", and the album also has contributions from Sonny Curtis and Glen Hardin, Beth Nielsen Chapman and Griffith's own band, The Blue Moon Orchestra.  The song "Waiting for Love", written by Griffiths, from "Blue Roses from the Moons" was picked out by Griffiths as giving the singer a "brief moment of being Edith Piaf". Lone Star State of Mind is Nanci Griffith's fifth album, and her first with a major recording label.  Griffith's music took a turn from her original folk music base into more commercially viable country music.  For this album, she enlisted the talents of veteran country producer Tony Brown.  The album garnered her first appearance on the Billboard Country charts, rising to #23 on the Country Albums chart, and is her highest charting album.  The title track, "Lone Star State of Mind," became the first of only three Griffith singles to enter the Top 40 of the Billboard Hot Country Singles chart.  It peaked at #36, while two other singles from the album, "Cold Hearts/Closed Minds" and "Trouble in the Fields", reached #64 and #57 respectively.  "From a Distance" failed to chart because it was released only as a promotional single in the USA. Daniel W. "Danny" Flowers (born 1948, Henderson, North Carolina) is an American songwriter, recording artist, and guitarist who is best known for his own songs that have been hits for other musicians.  These included "Tulsa Time" for Don Williams and Eric Clapton; "Back in My Younger Days" for Don Williams; "Gulf Coast Highway" for Emmylou Harris, Willie Nelson, and Nanci Griffith (co-written with Griffith and James Hooker); and "Before Believing" from Harris' "Pieces of the Sky".  Flowers has also enjoyed a solo recording career including the 2007 album, "Tools for the Soul".  From that album, "I Was a Burden" was recorded by the Blind Boys of Alabama featuring Lee Ann Womack. Winter Marquee is a live album by folk singer Nanci Griffith.  Recorded live during the "Clock Without Hands" tour in spring 2002, this album grew from the original wish to capture just one live song (Phil Ochs' "What's That I Hear") into a 14 track live CD album , Griffith's first live recording since "One Fair Summer Evening" (1988).  On May 29, 2002, at the historic Tennessee Theatre, Knoxville  a live performance was filmed, and released on DVD under the same name.  During the recording of both the album and the DVD, Griffith is joined on stage by Emmylou Harris, Tom Russell and Andrew Hardin. The Best of Nanci Griffith is a UK album release, which is very similar to "" but with several different tracks.  Two of the tracks on "The Best of Nanci Griffith" had previously never been released on any album .  The first of which "Tumble And Fall", was later released on "The Complete MCA Studio Recordings".  The second previously unreleased song "The Road To Aberdeen" was recorded live at The Royal Albert Hall, London in June 1993.
