MASTIV was Formed in the spring of 2008 by Steve Thiriot (Vox/Keys), with founding members Chris Whitney (Guitar/Vox) Lance Isbell (Drums), and Chris Meyer (Bass) They created a very unique style of metal, welding together elements of Hard Rock, Thrash, Metalcore, and Trance. After a few line up changes, adding Jonathan Rojas, (Lead Guitar/Vox) George Russell, (Drums) & Nick Langlois, (Rhythm Guitar) in 2012, MASTIV played many successful shows including opening for FEAR FACTORY.

Plans were in the works to revive MASTIV with all original members in spring 2015 when sadly, founding member Lance Isbell passed away from a heart attack in July of 2015. 

In fall of 2016 Steve Thiriot reached out to founding Members Chris Whitney, and Chris Meyer, to reform MASTIV and honor they're fallen band mate. Both were unable to commit due to other important obligations. Chris and Chris gave Steve they're blessing to continue on.

November 2016 started the rebirth of MASTIV. Steve invited long time friend James Hoover (Drums) to join him on this new chapter of MASTIV adding Nikki Rangel (Bass)

In August of 2019 MASTIV Added Jason Hughes (Lead Guitar) and Melaina Noyes (Rhythm Guitar) that complete's the  current line up of MASTIV.

Nikki’s music knowledge started at the age of 9, playing the violin for the school orchestra. From there she moved to the piano and taking lessons for about 6 years. Soon after, her love for the alternative rock and grunge music of the 90s made her want to learn the guitar. After a few high school and college guitar classes she continued to occasionally play the guitar and piano recreationally. All the while learning and listening to many genres of music and admiring her favorite bands, National and a Local.Fast forward many years, she received the opportunity to learn the Bass with a local band and possibly become a member. Being it a dream of hers to play with a band, she jumped at the chance. She practiced hard, learned songs and helped write new ones. She became a proud member of an amazing group of people. That band is MASTIV!
