This week, Today’s Top Tune hand-picks some of the artists playing This Ain’t No Picnic , going down Aug. 27 and 28 Brookside at the Rose Bowl. To kick off the festivities, we turn to Puerto Rican, LA-based artist Pachy Garcia, best known as Pachyman to fans. A lifelong student and lover of dub/reggae, Pachyman packs a punch as both a one-man band and accompanied by his group, as we witnessed at the Hammer Museum for KCRW’s Summer Nights and on his 3 Song Story on FREAKS ONLY. Take a taste with “All Night Long” featuring Brazilian shoegaze artist Winter.
