Absolutely love it - great composition, love the instrument choices, the arrangement works beautifully...
There are two little things that got to me a little as I listened to it: At 01:11, you are removing the bass section and the off-beat high piano chord is a little disorienting. It's better on a second listen, but the first time utterly confused me with the switch from a clear rhythmic structure to this dominating syncopation. The other thing is the same high piano chord that keeps going from 1:11 to the end. It might be a conscious choice, but I could see myself become really annoyed with it if I had to listen to that part on loop for some amount of time.
Despite these two little hangups, "Heat up the Ovens" will be one of the pieces from this jam that my immediate social circle will be forced to listen to.
