Blast is my favorite rapper that came out of Oakland in the 2010s. His discography is hit and miss but he got some good projects, his features are always dope. A lot of his best songs/videos never ended up on his mixtapes/albums... the director he fucked with most of the time (Jayswetwork) closed his youtube channel so a lot of Blast's material is gone.
His most lyrical project was M.A.S.S.E.R.A.T.I, skip the Mixtape Mob version and cop this one:
Blast Holiday - M.a.s.s.e.r.a.t.i Hosted by Chris Mixx // Free Mixtape @ DatPiff.com
His best all around projects are Coldest Winter Ever, Voices of the Underworld (Thizzler version) and Bobby Drake Vol. 2. If you fuck with L'z you should also check out the Conversations mixtape he did with Blast.
EDIT: the song you posted is off the Dragon Slayer mixtape, its a hit or miss project but there's some dope songs on it.
