The Festal Shout is a street punk band which reminds me of Flatfoot 56 or Hanover Saints. If you want to read a cool review see this article https://www.indievisionmusic.com/reviews/festal-shout-tumultuous-noise-ep/ . The bands name comes from Psalms 89: 14-18 ESV
Righteousness and justice are the foundation of your throne; steadfast love and faithfulness go before you. Blessed are the people who know the festal shout, who walk, O Lord, in the light of your face, who exult in your name all the day and in your righteousness are exalted. For you are the glory of their strength; by your favor our horn is exalted. For our shield belongs to the Lord, our king to the Holy One of Israel.
