On January 19, 2015, TLC announced their plan to release their fifth and final album with the launch of a Kickstarter campaign. They asked fans to help finance the project by donating a pledge of at least $5 to reach their goal of $150,000. In less than 48 hours, they surpassed their goal and become the "fastest most funded pop project in Kickstarter history". Among other artists who donated were New Kids on the Block (donating $10,000), Katy Perry (donating $5,000), Soulja Boy, Bette Midler and Justin Timberlake. The Kickstarter campaign raised a total of $400,000. In an interview published following the end of the campaign, Watkins and Thomas clarified that they would never split up following the release and promotion of the album, and that they would continue to perform together as TLC. In May 2015, TLC embarked on a North American tour with New Kids on the Block and Nelly titled The Main Event Tour. It was their first tour in 15 years since the completion of Fanmail Tour in 2000. Subsequently, TLC embarked on TLC 2016-17 Tour and I Love the 90s: The Party Continues Tour. During the development of their album, they petitioned Lisa Lopes' brother Ron Lopes for assistance with making Left Eye's presence on the album a possibility since she had an abundance of unreleased material. However, while being interviewed by Toronto music station 93-5 The Move on September 21, Thomas stated, "Actually on the last album after she passed away we went through a lot of her raps and used those then. I don't think so because we've already done that." On October 28, 2016, TLC released two new songs off of the new album called "Joyride" and "Haters" in Japan. The former hit number one on the iTunes R&B chart in Japan. For the first time ever, on December 8, 2016, TLC performed "Sleigh Ride" with surprise guest Missy Elliott along with their latest song "Sunny" on Taraji's White Hot Holidays, a holiday special on Fox hosted by actress Taraji P. Henson. Their fifth and final studio album, TLC, was released on June 30, 2017. It was reported to have collaborations from Dallas Austin and Kandi Burruss. The album's first single "Way Back" featuring Snoop Dogg was released April 14 to all major digital music outlets and streaming services, but not to radio. The single was produced by D'Mile and released via TLC's newly formed independent label 852 Musiq which is distributed through RED Distribution in the US. On May 9, 2017, TLC made their UK Debut at London's KOKO. Ultimately, TLC sold 12,000 copies domestically in the first week.
