Career
2013: The X Factor
Alex & Sierra auditioned in New Orleans, Louisiana, making it to the next round after wowing the judges with a sultry version of Britney Spears' "Toxic". They continued on to the top 40 and received Simon Cowell as their mentor. For the Four Chair Challenge, Alex & Sierra took on the John Travolta/Olivia Newton-John classic "You're The One That I Want" from the 1978 musical film Grease. The judges praised the duo for putting their own twist on the song. Kelly Rowland and Paulina Rubio felt the performance was "nice" and said they had "sexiness" to them, while Demi Lovato told them they were one of their favorite acts but questioned the future and their relationship.

Why this record matters
The phrase “band” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q15623477. VIAF identifies the subject as 311778360. The Library of Congress control number is no2014150646. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1991, 2014, 2016 and 2017.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
