TLC fans have grown impatient with the iconic girl group as they wonder where is the new music they promised.

Back in January, T-Boz and Chili pleaded with fans to help fund their fifth and final album. Uninterested in taking the label route, the two surviving members asked fans to donate to the group’s Kickstarter, in hopes to raise $150,000. The group was able to exceed their goal and raise $430,000 with a $5,000 donation from Katy Perry.

TLCWith the financial part having been handled, loyal fans are wondering when will they hear any new music? According to the group’s Kickstarter page, the album was set for release at the end of 2015, but has been pushed back to 2016. For some fans, that’s just not good enough, and they took to Twitter to air their grievances with the Grammy-Award winning group.
