Daves solo is shockingly bad on this one. I can sort of hear what he's trying to do, it sounds like he's trying to be the play the polar opposite of Adrians solo. Adrians is very loud, in your face and aggressive with a heavily processed tone. Daves is quiet, timid, and his tone is very dry.
Unfortunately his solo sounds like a beginner who has just learnt his first scale and is trying it out over a backing track that he's never heard before and is just trying to find notes that work. The first note of the solo just doesn't work well, he bends up to a B as the key is changing back from D minor to A minor. When the key changes like that you want a good solid note (maybe an A, E or C), a note that would work in the previous key but works well over the first chord of the new key.
Sorry for ranting but I don't feel this solo works. Adrian makes Dave sound like an amateur.
