On Thursday, the maple leaf flag flew proudly during Canadian Grammy Night in Hancock Park, where such northern-neighbor talent as Yukon Blonde, In-Flight Safety and Chantal Kreviazuk performed on the grounds of a baronial estate that might best be described as English Revival. The affair has become a key destination of a Grammy Week party train that continues to gather steam every year.

James Villeneuve, the consul general of Canada who co-hosted the evening, says his teenage kids keep him up to date on the music scene. And he’ll be rooting for the home team on Grammy night, represented by Drake, Arcade Fire and Deadmau5. “My son is really into classic rock, too,” says Villeneuve. “He plays guitar, and he takes me up to Amoeba Records whenever he gets money from his grandparents. He has albums I probably threw out that he’s now paying $40 for.”

Meanwhile, at the Hotel Cafe in Hollywood, the four-night stand of the Roots Grammy Jam sessions culminated with a bill that included LeCrae, Lolawolf, Kool & the Gang and Liv Warfield. The intimate venue, dubbed “the hot box,” was jam-packed, with 700 people left in the lurch on Cahuenga Boulevard who couldn’t get in.

The Roots, led by Questlove on drums, staged a kind of old-school soul revue clinic, with the requisite punch of a three-man brass section. Surprise guests kept the event going till after 1 a.m., including MC Jamie Foxx, who performed “Blame It on the Alcohol”; Nick Jonas, who crooned his hit “Jealous”; and Queen Latifah, who displayed equal chops as a jazz singer and rapper.
