The 42 most memorable pop music moments of 2009: Part VII

Drum roll please for the final installment...

Best local jazz, identical twins division: Twin brothers Nels and Alex Cline both released new albums in 2009, recorded over the same time period and issued on the same day. Nels might have earned more attention for his brilliant solo guitar excursion “Coward,” but drummer Alex’s consciousness-raising and equally adventurous ensemble journey, “Continuation,” is also not to be missed.

Most meditative record to come out of a non-meditative city: Filled with dense, Terry Riley-inspired drones, soothing electronic pulses and guitar filigrees that recalled the acoustic folk of Leo Kottke, the Brooklyn duo Mountains inspired any number of candlelit journeys of internal discovery with the dense, immersive “Choral.” Not advisable while operating heavy machinery.

Most unlikely megastar producer: David Guetta. Long beloved by the “Jersey Shore” cast and its ilk for his Ibiza-killing club hits, Guetta saw blood in the water as soon as rappers started tilting toward the trancey four-on-the-floor beats he practically owns a patent on. He’ll be cashing his paycheck for the Black Eyed Peas’ “I Gotta Feeling” for the rest of his life, and he sported 2009’s best pickup line on “Sexy Chick,” courtesy of guest vocalist Akon: “I’m trying to find the words to describe this girl without being disrespectful.” (AB) Photo: Getty Images

Best future soundtrack for a smoky robot lounge: Composed of four long “Patterns” created by electronic producers Moritz von Oswald, Vladislav Delay and Max Loderbauer, the Moritz von Oswald Trio’s “Vertical Ascent” discovered a new metallic world through live percussion, swirling keyboards and tangled, echoing polyrhythms. This is the sound of machines pumping real blood. (CB) Photo: Honest Jon's

Best cantankerous song on the economic meltdown and government’s efforts to remedy it: “Fork in the Road,” the title track from Neil Young’s latest studio album. “There’s a bailout coming,” the Rock and Roll Hall of Famer sings knowingly, “but it’s not for you.” (RL) Photo: Randi Lynn Beach
