The answer to this is TLC. The name TLC comes from the initials of the names of the member. T for T-Boz, L for Left Eye, and C for Chili. The group was able to make some success hits. Their album CrazySexyCool sold really well. There were a lot of issues that the members have experienced before with their management and label but they were still very popular then.
You just need to sing a few lines of “Waterfall” and people would immediately recognize it. Left Eye, also known as Lisa Lopes died back in the year 2002 because of a vehicular accident. She tried to do defensive driving but failed. She suffered from massive neck injuries. She and the rest of the members are still known by those who loved their songs during that time.
