The Vanguard Testimonials or TVT is an anthology of single album releases, an accompanying photobook and interview for each member of seVenwrld. The next testimonial is released on the same day as the member's solo single.

History[]

On April 10, 2024, cosmichaus unveiled The Vanguard Testimonials; a project wherein each member of seVenwrld could release a solo project consisting of a single album, a photobook and an interview. In the same announcement, it was revealed that the 'testifying member' (the member being focused on as part of the anthology) would promote on music shows for a week and that the testimonial would not count as their solo debut.

On June 17, 2024, Solyeon was revealed as the inaugural 'testifying member.'

As of July 2024, little is known as to the selection process of the Testimonials.

Testimonial Releases[]

  • SOLYEON - June 17, 2024
  • ITTO - July 31, 2024
  • TIAGO - September 17, 2024
  • YEJUN - January 3, 2025

Cosmos' Call[]

Cosmos' Call is a track featured on all Testimonials. A cosmic, airy-driven song, it features both a singing and a rapping part. The 'testifying member' will assume the role he is best at out of the two whilst their feature will assume the other. Although the instrumental remains the same, the vibe of each rendition of the song is changed to suit the 'testifying member' the best.
