Every so often the International Man Of Crate-Digging Mystery who is bumrocks.com uncovers a track that lifts you out of your shoes and attaches electrodes to your head. He (or she) has done it again, with "Desintegracion", by Tabaco, an awesome slice of hard-edged psychedelic rock. Googling around reveals that it is from an album of the same name, from 1971, and that Tabaco hailed from Spain. Unsurprisingly, Tabaco otherwise remain somewhat obscure. (There appears to have been a two-CD reissue of this a few years back; the danger, I have found, with such surprising one-off tracks is that the rest of the associated album doesn't have what it takes. See, for example, "Edge Of Time" by Dom.)
