Can't choose any three, here are a few that pop into my mind when I think of the question:
Journeys II (All of them aside for half of Vol. 4, but I'm restricting to one per singer/performer)
Avraham Fried-Bracha Vehatzlacha
MBD- Lulei Sorascha
8th Day- Brooklyn
Shwekey 2
Issac Bitton- "songs for a brother" Vol. 1
Baruch Levine- Hashkifa
Miami Boys Choir- One by One
