[Tango-L] Acanyegando

[Igor Polk]

Listening to classical "Piazzolla: Symphonic works" Chandos CHAN 10049,
http://www.chandos-records.com/details05.asp?CNumber=CHSA%205006
( very dark, but shivering CD )
I saw the first piece named "Tangazo: Variations on Buenos Aires" was
described as
"Lento-Allegro-Lento-Allegro-Mas lento y muy acanyegando".

I do not know Spanish, what does it mean, acanyegando ?

Igor.
