Final answer:
Chubby Checker did not establish Philles Records; it was founded by Phil Spector and Lester Sill. The statement in the question is false.
Step-by-step explanation:
The statement that Chubby Checker established his own independent label, Philles Records, at age 21 is false.
Chubby Checker is indeed a successful recording artist known for popularizing the twist dance style with his cover of Hank Ballard's song "The Twist" in the early 1960s.
However, Philles Records was actually founded by Phil Spector and Lester Sill in 1961, and there is no record of Chubby Checker ever founding this or any other record label at age 21.
