。
She paid to listen to the concert.
Literal
She [topic-は] money [object-を] paying-(and), recital [object-を] listened-to.
The te-form 払って ('having paid') chains causally into the second clause — 'paid, and as a result, listened.' 演奏会 (literally 'performance-meeting') is the formal word for a musical recital or concert; the loanword コンサート also works. 聞く ('to listen') is the verb of choice for receptive listening; 聴く (same reading) emphasizes attentive listening, the kind a paying audience does at a recital. The kanji choice 聞く here is the unmarked default.
