There are at least two bands with the name Zu or ZU:

1. Zu is an Italian experimental rock band.
2. ZU is an Indonesian rock band.

1. With their original line-up (since 1997) of drums (Jacopo Battaglia), bass (Massimo Pupillo), and saxophone (Luca T. Mai (Mombu)), the trio from Rome, Italy gradually developed into their current form of highly intricate, experimental, metal/math/no-wave/free/noise/punk/jazz inspired work, breaking from the narrow confines of given music genres, and incorporating a wide array of influences into a unique sound.
