DJ Sun isn't hard to find. He has a residency most evenings of the week, either solo or with the crew from his long-running Saturday-night KPFT show Soular Grooves. As affable as he is industrious, in 20 years Sun has become a soft-spoken cornerstone of the Houston music community, often dispensing advice to or collaborating with a host of younger local musicians. One thing he's not is especially prolific, recordwise. So to reintroduce himself before his new LP, One Hundred, drops January 19 — it's his first release since 2009's Para EP — Sun has been keeping a journal at www.soulargrooves.com. Whether the daily entry is a video tour of his preferred Houston haunts or simply a list of all the people Sun has opened for, it's an enlightening glimpse into the career of an artist whose talents stretch far beyond the turntables.
