Tiedo Groeneveld – adding his surname for activities other than his solo career – is also busy in other musical fields.
He has provided music for various theatrical stage productions, composed for television ads, occasionally plays with ad hoc ensembles and has also been spotted as a sound technician (but only if he enjoys the music) and as producer/arranger.

Since January 2009 Tiedo is working on a regular basis with theatre company NNT, also hailing from Groningen. More info on the NNT company here.

Tiedo has recorded and produced an album for HETTE, entitled "Frozen Grass", released in December 2009.
