There are perhaps no harder working musicians in D.C. than Janel Leppin and Anthony Pirog. Both are gifted and constantly evolving multi-instrumentalists, and both of their names are synonymous with nearly every pocket of the District’s diverse, bustling music scene—from jazz to avant-garde and experimental, and even to indie rock and DIY punk (at least in involvement, if not in sonic practice).

But their main focus has always been the music they’ve made together. Over the course of two albums, they’ve taken their encyclopedic musical knowledge and training from around the world and funneled it into their own playing, which has mostly focused on Pirog’s impressive guitar chops and Leppin’s exquisite cello skills.

Leppin and Pirog’s forthcoming third LP, Glover Park, will come out via Leppin’s newly launched Wedderburn Records. The newest track off that record is “Sweet and Sour,” and it marks another evolution for the duo into far dreamier, experimental territory.

Ambient, layered soundscapes ebb and flow as if they are, as Leppin sings, “in a dream.” Her delicately hushed vocals float over soft synth melodies, like the sonic companion to Grouper, the drone-y, ambient solo project of musician and artist Liz Harris. Midway through the song, the dream ends and the music comes alive with a simple beat and Pirog’s shimmering guitar tones.

Janel and Anthony will play a benefit concert in support of Union Arts at 8:30 p.m. on Feb,. 19th with Escape-ism and Adriana-Lucia Cotes. 411 New York Ave. NE. More info here.
