Query: A forgotten, underground classic (5 Stars)

Very rarely is such amazing hip-hop funk condensed in to the minute tracklisting of 12 songs but on Main Source's Breaking Atoms, it is done with amazing finesse. The only person to condense it even further would be Nas on Illmatic, and coincidentally, he is featured here on his first ever album appearance, "Live At The Barbeque." Even without that song, this album stands as one of rap's shining moments with the production team of Sir Scratch and King Kut on the turntables. Their dense sonic collage is something one has to hear to believe. It is, unfortunately, a sound that has never been duplicated on any other record. It is hard to believe that an album such as this could fall into the cracks of music history but it makes the album that much more special. Owning a copy of this album is like holding a piece of rap history and anyone with the great fortune to have this masterpiece should never let go of it.
