Slaughterhouse is finished.
They had some sort of traction around 2/3 years ago but lost it when that debut completely flopped. Music was below par and they've not been able to recover since.
They became irrelevant when people realized hip hop didn't need to be saved. They started making noise when the ring tone shyt was dying, right when Drake came out. Not saying Drake saved anything but labels started looking for their own Drake after he blew. That opened the door for Cole, Kendrick, KRIT, etc. The underground was also bubbling with Bronson, Spitta, Danny Brown, etc. Marcberg came out a year later in 2010.
Basically hip hop suddenly got way more interesting for both the mainstream and underground. SH became irrelevant, blogs were no longer running stories about them saving hip hop, and all was right with the world.
