Most ICCA regions have one more week of quarterfinal action to go, but the UK Semifinal lineup are set, with nine groups earning a spot on the stage at New Wimbledon Theatre in London on March 31.

Following their strong showing in Quarterfinals, two groups are representing the University of St. Andrews and three groups are representing the University of Bristol, including The Bristol Suspensions, who earned the highest score in Quarterfinals with a score of 433.

Here's a look at the ICCA UK semifinalists:

The Northern Lights of Durham University

Just 4 years old, this mixed group enjoys competition and has put out several stellar music videos. The group also released the EP "Bright Lights Small City" in 2016.

The Other Guys of University of St. Andrews

Pushing to be the best of Scotland a cappella since 2004, The Other Guys have graced big stages in the UK. They combine classical, contemporary, and a little humor for their unique sound.

The Accidentals of The University of St. Andrews

The ladies of St. Andrews also bring an immense amount of talent to the stage. Founded in 1994, the group won the 2015 Scottish A Cappella Championship with its signature style and creativity.

The Bristol Suspensions of University of Bristol

Just over 3 years old, this group already has several accolades under its belt, including the title of 2016 Voice Festival champion, an appearance on BBC One’s "Pitch Battle," and a previous appearance on the podium at ICCA Semifinals. Going into this year’s event with the highest score in Quarterfinals, The Bristol Suspensions are definitely a group to watch.

Pitch Fight of University of Bristol

These fierce competitors took home second place at their quarterfinal but also walked away with Outstanding Soloist and Outstanding Choreography. Not bad for a group that still considers itself to be brand new.

Academy A Cappella of University of Bristol

Total newcomers to the ICCA, this group was recently featured on Sky 1 HD’s "Sing: Ultimate A Cappella."

The Rolling Tones of King’s College London

One of the more seasoned groups in the pack, The Rolling Tones have appeared on big stages at the Olympics, International Women’s Day, Edinburgh Fringe Festival, and the Voice Festival UK. In their first time at ICCA last season, they earned the highest UK quarterfinal score ever recorded and are looking to better their second-place finish at Semifinals last year.

The Oxford Alternotives of Oxford University

Founded in 1993, they were the first group to offer an alternative to traditional choir at Oxford. They’ve appeared on BBC 1, toured the U.S., and have won numerous awards for their arrangements and choreography.

The Songsmiths of University of Leeds

Rounding out the competitors, this mixed group from Leeds has appeared at the National Finals of the Voice Festival UK for three years running, capturing top honors in 2016.

The winner of the UK Semifinal will advance to the ICCA Finals  at The Beacon Theater in New York City on April 21.
