COMPASS at CERN uses hadron and muon beams with up to 200 GeV/c momentum, produced from the SPS proton beam, for investigations in hadron structure and spectroscopy. From a pilot run with a 190 GeV/c pion beam on a lead target, various results are presented. In the region of low momentum transfer, interference of photon-exchange and strong production of the a{sub 1}(1260) and a{sub 2}(1320) resonances is observed, revealing the different nature of the two interactions.
