Question: Which American recording engineer recorded Van Morrison's fifth studio album?
Context: Saint Dominic's Preview is the sixth studio album by Northern Irish singer-songwriter Van Morrison.  It was released in July 1972 by Warner Bros.  Records. " Rolling Stone" declared it "the best-produced, most ambitious Van Morrison record yet released." The Skiffle Sessions – Live In Belfast 1998 is a live album by Northern Irish singer-songwriter Van Morrison, with Lonnie Donegan and Chris Barber, released in 2000 (see 2000 in music).  Lonnie Donegan had played with the Chris Barber jazz band when he had his first hit with "Rock Island Line"/"John Henry" in 1955.  He had been a childhood influence on Van Morrison, who had first performed in his own skiffle band with schoolmates when he was twelve years old in Belfast, Northern Ireland.  This would be Donegan's first studio album in twenty years; reviving his career until his death in 2002. Duets: Re-working the Catalogue is the 35th studio album recorded by Northern Irish singer/songwriter Van Morrison.  It was released on 13 March 2015 on RCA Records.  Produced by Van Morrison along with Don Was and Bob Rock, it consists of songs previously recorded by Morrison this time recorded as duets.  Performances include the artists Bobby Womack, Steve Winwood, Mark Knopfler, Taj Mahal, Mavis Staples, Michael Bublé, Natalie Cole, George Benson, Gregory Porter, Clare Teal, P.J. Proby, Joss Stone, Georgie Fame, Mick Hucknall, Chris Farlowe, and Morrison’s daughter Shana Morrison. The Best of Van Morrison Volume 3 is a compilation album by Northern Irish singer-songwriter Van Morrison, that was released on 11 June 2007 in the UK with a digital version released in the U.S. on iTunes Store, on 12 June 2007.  Manhattan/EMI Music Catalog Marketing released the CD version of the album on 19 June 2007 in the United States.  This new two-disc collection of 31 tracks has been compiled by Morrison himself.  It offers an overview of his large volume of material since the release of "The Best of Van Morrison Volume Two" in 1993.  The album's thirty-one tracks include previously unreleased collaborations with Tom Jones ("Cry For Home") and Bobby Bland ("Tupelo Honey") as well as duets with John Lee Hooker, B.B. King and Ray Charles.  The 2003 duet with Ray Charles is "Crazy Love" a song originally recorded on Morrison's 1970 album "Moondance".  "Blue and Green" was previously donated to be used on the charity album "", which raised money for relief efforts intended for Gulf Coast victims devastated by hurricane Katrina.  The duet with Tom Jones, "Cry For Home" was taken from the same recording sessions that produced the "Sometimes We Cry" duet between the two artists, which featured on Jones' successful album "Reload".  "Cry for Home" was released as a single on 4 June 2007 in the UK, and was followed by "Blue and Green" on 27 August. Wally Heider (1923–1989) was an American recording engineer and recording studio owner (Wally Heider Studios.)  After a distinguished career as an engineer in the 1940s [source?]  and 1950s, he was instrumental in recording the San Francisco Sound in the late 1960s and early 1970s.  A significant number of Rolling Stone Magazine's Top 500 albums were recorded in his studio including "Volunteers" by Jefferson Airplane, "Everybody Knows This Is Nowhere" by Neil Young with Crazy Horse, "Déjà Vu" by Crosby, Stills, Nash & Young, "Electric Warrior" by T. Rex, "Tupelo Honey" by Van Morrison, "American Beauty" by the Grateful Dead, "Green River" by Creedence Clearwater Revival and "Abraxas" by Santana. Veedon Fleece is the eighth studio album by Northern Irish singer-songwriter Van Morrison, released in October 1974 (see 1974 in music).  Morrison recorded the album shortly after his divorce from wife Janet (Planet) Rigsbee.  With his broken marriage in the past, Morrison visited Ireland on holiday for new inspiration, arriving on 20 October 1973 (with his fiancee at the time, Carol Guida).  While there he wrote—in fewer than three weeks—the songs included on the album (except "Bulbs", "Country Fair" and "Come Here My Love"). Tupelo Honey is the fifth studio album by Northern Irish singer-songwriter Van Morrison.  It was released in October 1971 by Warner Bros.  Records.  Morrison had written all of the songs on the album in Woodstock, New York, before his move to Marin County, California, except for "You're My Woman", which he wrote during the recording sessions.  Recording began at the beginning of the second quarter of 1971 at the Wally Heider Studios, San Francisco.  Morrison moved to the Columbia Studios in May 1971 to complete the album. His Band and the Street Choir (also referred to as "Street Choir") is the fourth studio album by Northern Irish singer-songwriter Van Morrison.  It was released on 15 November 1970 by Warner Bros.  Records.  Originally titled "Virgo's Fool", "Street Choir" was renamed by Warner Bros. without Morrison's consent.  Recording began in early 1970 with a demo session in a small church in Woodstock, New York.  Morrison booked the A&R Studios on 46th Street in New York City in the second quarter of 1970 to produce two sessions of songs that were released on "His Band and the Street Choir". A Sense of Wonder is the fifteenth studio album by Northern Irish singer-songwriter Van Morrison released in 1984.  On first release, original pressings had to be recalled when the W. B. Yeats estate refused to allow Morrison's musical version of the poem "Crazy Jane on God" to be included, as they believed his poems should only be set to classical music.  Morrison substituted "If You Only Knew" for the Yeats' recording.  (Later, perhaps due to Morrison's efforts, Yeats poems would be put to rock settings on a whole album). Born to Sing: No Plan B is the 34th studio album recorded by Northern Irish singer/songwriter Van Morrison.  It was released on 2 October 2012 on Blue Note Records.  Produced by Van Morrison, it marked his first studio album of original songs since 2008's "Keep It Simple".
