The Blues Festival in the Forest doubles up for year two.

If spending a Sunday afternoon with an adult beverage in one hand and gourmet foodstuffs in the other while listening to top-shelf blues players in a beautiful location sounds good, this is a worthy Father’s Day celebration.

The second annual Blues Festival in the Forest has basically doubled in both size and scope. Where there were two bands there now are four; one stage has morphed into two, and the amount of entertainment for kids has easily doubled.

The brainchild of Poppy Hills General Manager Brad Shupe, last year’s debut was conceived in the wake of the passing of the late great blues icon B.B. King. Event planners at Poppy Hills and members of the Monterey Jazz Festival team scrambled to produce the party and secure entertainers in a tight, three-week window.

“This time we’ve had a whole year to work on this,” Shupe says, “and it shows.”

Some 400 people attended the 2015 soiree, and event organizers hope to – yes – double that number this year. This year the gig lands on 2-plus acres, canvassing the entire driving range.

San Jose-bred and now Bay Area-wide stalwart blues guitar ace Chris Cain and his band headline this year, including a special collaboration with guest guitarist Daniel Castro, who is a bona fide headliner in his own right.

Cain, whose 1987 debut album Late Night City Blues garnered an unprecedented four W.C. Handy award nominations, has since gone on to stages large and small domestically and internationally. Cain’s latest CD, Hall of Shame, displays a unique amalgamation of funk, gospel, jazz and sophisticated blues.

Rounding out the bill are longtime Santa Cruz bluesman Al James, 2012 American Idol finalist Wolf Hamlin and his band The Front Porch Drifters, and the Monterey Jazz Festival High School All-Star Combo, a smaller group of players culled from the much larger All-Star Band.

Like last year, the event is a fundraiser, this time to support visits to L.A. by the MJF High School All-Star Band and High School Honor Vocal Jazz Ensemble, who perform there the last week in June. “The program gives the kids a brief thumbnail sketch of what it is really like to be an on-the-road professional musician,” says Jazz Festival spokesman Timothy Orr.

Greatly augmented this year are kid-friendly activities like a jump house, trampolines and face painters. Fold in gourmet food trucks, wines from Folktale Winery, tequila by El Jefe, vodka from Ketel One and a beer garden by Mad Otter, and there’s an afternoon of revelry. Dads, you can double down on that.
