Playing in the concert focusing on one’s own group (12)

I believe the answer is:

ethnocentric

I'm a little stuck... Click here to teach me more about this clue!

'focusing on one's own group' is the definition.
I can't judge whether this definition defines the answer.

'playing in the concert' is the wordplay.
'playing' indicates an anagram.
'in'+'the'+'concert'='intheconcert'
'intheconcert' anagrammed gives 'ETHNOCENTRIC'.

Can you help me to learn more?

(Another definition for ethnocentric that I've seen is " Seeing other cultures through one's own".)

I've seen this clue in The Hindu.
