“One of the only.” It’s a plague on modern English.
What we mean to say is “one of the few.”

The “only” people who play on this record are the people who play on this record. There’s no point in using the word “only” to describe these people. They’re already the only ones.
But if we want to make the point that there are just a few folks playing on the record, then it makes sense to describe Turrisi as “one of the few.”
(How did this “one of the only” plague get started? It was probably the same guy who coined the term “most unique.” Gah!)
