The one and only singer Patti LaBelle called “silver throat” has died.

Sarah Dash, a vocal powerhouse who gained international fame in the 1970s with the groundbreaking R&B trio Labelle, was 76.

The Trenton, N.J., native’s death was unexpected and the cause was unknown at presstime.

LaBelle, who remained close friends with Dash since the group disbanded in the mid-1970s, revealed the two last performed over the weekend.

During the early 1960s, Dash became a co-founder of Patti LaBelle & The Bluebelles.

After gaining notoriety for their soaring vocals on popular songs as “Down the Aisle (The Wedding Song),” “Danny Boy,” “You’ll Never Walk Alone” and an evocative rendition of “Somewhere Over The Rainbow,” the group refashioned itself into the glam-rock, afro-futuristic trio Labelle.
