Thus the Spanish produce individual performances (5)
I believe the answer is:
solos
'individual performances' is the definition.
(I've seen this in another clue)
'thus the spanish' is the wordplay.
'thus' becomes 'so' (synonyms).
'the spanish' becomes 'los' ('the' in Spanish).
'so'+'los'='SOLOS'
'produce' is the link.
(Other definitions for solos that I've seen before include "Pieces of music for one voice or instrument" , "Unaccompanied parts" , "Passages for one player" , "Musical passages for one instrument" , "Numbers" .)
