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.

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!
