Who needs instruments with voices like these?
The House Jacks aren’t just your run of the mill a cappella boy band group. They’re super slick and can improvise pretty much anything. Channelling their inner Frankie Valli as much as possible, their harmonies are smooth and they can pull some neat vocal tricks. Having appeared in the movie Pitch Perfect and on NBC's The Sing Off, they're now ready to take on London. Best available seating.
"A Cappella with attitude."
