Kicking off the party this Friday at the XPoNential Music Festival will be a set from Philly synthpop duo City Rain, who late last night released “Fleeting Smile,” a brand new instrumental song from their forthcoming Montage EP. You can grab a free download of the song below, check out the band’s Key Studio Session here, and catch their set Friday at 5:30 p.m. at the Marina Stage of Wiggins Park.
