Bands of America is headed back to Lucas Oil Stadium in Indianapolis for three full days of music, marching, and madness! During the massive 2017 Bands of America Grand National Championship, 50 bands will take the field on Thursday and Friday. Then on Friday evening we find out who gets another chance to perform on Saturday morning and afternoon! Once semifinals come to a close on Saturday afternoon, the top 12 will move on to a third and final performance in BOA Grand National Championship Finals!

Here are three bands you CANNOT miss on the second day of prelims on Friday.

7:30 AM EST - Flower Mound (Texas)

One of the six bands representing Texas in this weekend's Super Bowl-sized event is the Flower Mound band from Flower Mound, Texas. In what was one of the most highly competitive and impressive marching band competitions to take the field, the BOA San Antonio Super Regional, Flower Mound earned an impressive sixth place with a finals score of 94.550. With their finish in the Alamodome, Flower Mound moved within a point of Avon (IN), a top contender for this weekend's festivities.

Flower Mound's 2017 show is entitled "Fractured Moments," featuring music selections by Philip Sparke, Peter Graham, Robert Lowry, and Stephen Melillo. From grays and whites to bright blues, pinks, oranges and reds, this band's uniform and prop selections will catch your attention early and often during their 7:30 AM EST performance time on Friday.

9:30 AM EST - Blue Springs (MO)

At the BOA St. Louis Super Regional last month, Blue Springs earned second place behind Broken Arrow (OK) with only a 1.25-point gap between the two! In their last trip to Grand Nationals in 2015, the Missouri band earned 10th and an 89.10.

Blue Springs' 2017 production is called "Burtonized." Check out this Facebook Live stream of the band from the St. Louis Super Regional!

2:45 PM EST - Marian Catholic (IL)

One of the most established bands in the Bands of America circuit is bringing its caravan from Illinois to Indy this weekend! In their long history, Marian Catholic have earned 19 BOA Grand National class champion titles and seven Grand National champion titles. Last season, they earned 12th place with a final score of 90.05, and so far this season, they have competed in Lucas Oil Stadium at the BOA Indianapolis Super Regional. They placed sixth, right behind Homestead (IN) and ahead of Centerville Jazz (Ohio).

Marian Catholic's 2017 show uses the music of Aaron Copland, Carter Pan, John Mackey, Eva Cassidy, and Alberto Ginastera. Check out this video of their phenomenal guard warming up before the Indianapolis Super Regional!
