The last track off of Tool debut EP, and features Paul D'Amour on bass! The song is about the notion that "religion is the opiate of the masses". And like many other Tool songs - like "Rosetta Stoned", the title of the song is perfect. It took me a while to realize what the title of the song actually meant, until I thought about that quote. I could go into a thing about how "Rosetta Stoned" is also a clever, perfect title, but that's not what you are here for!
This track has a pretty standard metal feel too it, although the arrangement is very unusual. All there verses kinda sound the same and it's almost as if every verse could be the chorus, given that they are always repeated twice and with such a flow that it immediately wiggles it's way into you head and never leaves. The bridge section - which is quite short - opened guest opportunities for the song. Back in the mid-90's Tool would have guest singers like Layne Staley, Tricky, Heitham Al-Sayed, and I think Zack de la Rocha, although that my have been a different tool song. My personal favorite is one that they did [url="https://youtu.be/6ybqA_wWXRQ?t=1h44s"]live in Paris in 2006[/url], where the whole bridge is done by the guest vocalist and it's just amazing.
I had the pleasure of seeing Tool live in Hamilton on May, 28th. And what they did with Opiate on that show (and by extension the whole tour) was to put the Maynard rant in the middle of the song. It's really interesting stuff and it's like listening to a whole new song. Instead of going into the traditional bridge section they turned it into a jam session that I can only assume are working parts for new material. This was not to brag about how I've seen Tool live (lol), but just to give another example about how they use the track as a foundation and a blueprint to do cool segues and explore new musical ideas.
One a final note. I'd recommend getting this EP on vinyl, if only for the soul reason that side B is double grooved, so you don't know if you are gonna get the actual track, or if you are gonna get the hidden track (if you don't know what double grooves are, just google it, it's really cool and I wish more bands would use it). As for this custom, YES the hidden track is there, but it's called a hidden track for a reason...
