Bermudian singer Ben Lusher, of the thriving New York band Thirdstory, has shot to new prominence sharing the stage with the artist Chance the Rapper.

The trio, which joined forces in 2014, backed Chance on The Late Show with Stephen Colbert, where the rapper launched a freshly crafted song that won applause from The Atlantic magazine.

Thirdstory toured as Chance’s background vocalists over the summer on his Be Encouraged tour, as the group told Billboard magazine.

The group caught the rapper’s eye after performing with R&B artist Eryn Allen Kane, and appeared with Chance on Saturday Night Live — leading to a place on his tour.

Mr Lusher told Billboard that the group was keen to build links with other artists.

“A lot of the relationships that we’re building on this tour are relationships that we want to continue,” he said.

A new album is expected this autumn, reprising established songs from their EP Searching, alongside new material. A release date has yet to be announced, Mr Lusher said.

The Late Show appearance on September 25 featured an untitled song finished only the night before.

The improvised creation was hailed as “mindbendingly impressive” by The Atlantic.
