Understanding the way confinement arises from QCD is nowadays one of the most important problems in strong interaction physics. A complete understanding will certainly require a meaningful comparison of QCD predictions to the extant and planned experimental data.

The ongoing effort to understand the baryon spectrum making use of a dynamical coupled-channels model will be reviewed. The latter is needed to incorporate the effects of the meson-baryon dynamics and thus unravel the complicated mixture of direct production processes and multistep production mechanisms.

I'll end up by outlining the necessity of a similar effort to disentangle the future data collected at the GLUEX@JLAB experiment which will permit the extraction of meaningful information about gluonic excitations.
