Pre leitmotif dredg not really worth bothering. Leitmotif itself is second best dredg for me, it is however much harder to get into then say el cielo or catch without arms
Since Orph got mentioned, I'll have to also mention the various demos that float around. There is one, I believe referred to as Industry Demo, that contains like 3 actual proper songs recorded between Leitmotif and El Cielo
