Heart of Imagination is the B-side of Be As One. In my opinion, Heart of Imagination is more interesting.
The synth starting at 1:10 is fairly standard for its time. I feel like I've heard it before, but I couldn't tell you where.
If it wasn't obvious that this is a BT track, the kicks starting at 2:39 give it away. I got Libra pres. Taylor - Calling Your Name vibes based on how we have an additional 9th kick every 2 bars. The section at 4:22 has even stronger BT vibes. Some parts of this track really do feel like an alternate version of Calling Your Name, but that's not necessarily a bad thing.
The deep bassline at around 6:52 is nuts. It's almost like a different track compared to the "Calling Your Name" section. I'm not too familiar with BT/Sasha's work from this era, but I imagine this is more Sasha than BT.
8:18 introduces the last major change, an X-cabs style synth that is also totally '90s. This synth appears briefly for a couple of bars and then comes back at 9:03.
10:03 onwards is the outro. Nothing too special here. It's just fitting for DJ mixes of then.
