The exploratory guitar patterns and progressive tempos of Philadelphia’s Caveman easily recall another indie-jazz combo of note: Medeski Martin & Wood. So it’s no accident that the four-piece finds itself opening for Mago, the side project of John Medeski and Billy Martin, over at University City’s Blockley Pourhouse this Wednesday. Last December, the band released its self-titled debut EP, and today’s we take the XPN2 Philly Local Philes on a mellow detour to immerse ourselves in the wandering vibes of “Dream Land.” Opening out on the humming tones of Brian Marsella’s organ, the pointed punctuations of John Lee’s lead guitar build up gradually alongside the chugging rhythm section of bassist John Buck and drummer Tim Keiper. It’s done at such a smooth, measured pace, by the time the song erupts around the 3-minute mark, you haven’t even flinched. Listen below; if you want more, catch them Wed. Nov. 30 at The Blockley and get blissfully lost.
