Question: Which artist or group is from the US, Billy Bragg or Incubus?

Context paragraphs:
Incubus (band): Incubus is an American rock band from Calabasas, California.  The band was formed in 1991 by vocalist Brandon Boyd, lead guitarist Mike Einziger, and drummer Jose Pasillas while enrolled in Calabasas High School and later expanded to include bassist Alex "Dirk Lance" Katunich, and Gavin "DJ Lyfe" Koppell; both of whom were eventually replaced by bassist Ben Kenney and DJ Kilmore respectively.

Grant Showbiz: Grant Showbiz (real name Grant Cunliffe) is a British record producer principally known for his work with The Fall, The Smiths, and Billy Bragg plus as an artist in his own right with Moodswings.  He continues his work with both Billy Bragg & The Fall to this day, having worked on more albums by both The Fall (15) & Billy Bragg (14) than any other producer.  Showbiz has been awarded Gold Records for The Smiths' "Rank", Billy Bragg's "Don't Try This At Home" and The Wilco/Bragg collaboration "Mermaid Vol.1", and received Grammy nominations for both Mermaid Avenue Vols 1 & 2.

Brewing Up with Billy Bragg: Brewing Up with Billy Bragg is the second album by Billy Bragg, released in 1984.

Talking with the Taxman About Poetry: Talking with the Taxman About Poetry is the third album by Billy Bragg, released in 1986.  With production by John Porter and Kenny Jones, "Talking with the Taxman About Poetry" featured more musicians than Bragg's previous works, which were generally little more than Bragg himself and a guitar.

The Internationale (album): The Internationale is a 1990 album by Billy Bragg.  Originally released on Bragg's short-lived record label, Utility Records, it is a deliberately political album, consisting mainly of cover versions and rewrites of left-wing protest songs. Although Bragg is known for his association with left-wing causes, this release is unusual; most of Bragg's recordings balance overtly political songs with social observation and love songs.

Back to Basics (Billy Bragg album): Back to Basics is a 1987 collection of Billy Bragg's first three releases: The albums "Life's A Riot With Spy Vs. Spy" and "Brewing Up with Billy Bragg" and the EP "Between The Wars".  This collection did not contain any new material, but did document Billy Bragg's early "one man and his guitar" approach.  The songs collected on this release demonstrate major recurrent themes in Bragg's work: highly critical commentary on Thatcherite Britain, laced with poetic love songs.  The collection was re-released in November 1993 on the Cooking Vinyl label.

Waiting for the Great Leap Forwards: Waiting for the Great Leap Forwards is a 1988 song by English singer/songwriter Billy Bragg.  The song was released as a single from the album "Workers Playtime".  Bragg was accompanied on the original recording by Martin Belmont, Bruce Thomas, Cara Tivey, Mickey Waller and Bragg's long-standing roadie Wiggy, with backing vocals by Michelle Shocked and Phill Jupitus among others.  The recording was produced by Joe Boyd with Wiggy.  The single had two songs on the b-side: a re-recording of Bragg's "Wishing the Days Away" featuring Tivey, and a cover of the Flying Burrito Brothers' "Sin City" featuring Hank Wangford, both produced by John Porter and Kenny Jones.

The Peel Sessions Album (Billy Bragg album): The Peel Sessions Album is an album by British rock artist Billy Bragg, released in 1991.  It compiles recordings from Bragg's various radio sessions for John Peel's programme, recorded between 1983 and 1988.

Levi Stubbs' Tears: "Levi Stubbs' Tears" is a song by Billy Bragg.  It was the first single released from Bragg's 1986 album "Talking with the Taxman about Poetry".  The song's title refers to The Four Tops lead singer Levi Stubbs, whose music remains a source of comfort to the protagonist through years of abandonment, injury, and domestic violence.

Billy Bragg: Stephen William Bragg (born 20 December 1957) is an English singer, songwriter and left-wing activist.  His music blends elements of folk music, punk rock and protest songs, with lyrics that mostly span political or romantic themes.  His music is heavily centred on bringing about change and getting the younger generation involved in activist causes.
