John Dwyer is a man of his word. When the OSEES frontman first announced the band’s upcoming Levitation Sessions sequel, he promised that the underground mainstays would mine their catalog for a “handful of never-before-played-live tunes & some new surprises.” Dwyer has already made good on that promise—even before the webcast’s April 10th premiere—with a video of the band’s live debut of “Stinking Cloud”.

Taken from OSEES’ 2011 album Castlemania, “Stinking Cloud” is a far cry from the high-intensity low-fi alternative rock on which Dwyer has built a sterling reputation. Instead, the song came as part of an experiment in 1960s psychedelia that completely separates itself from the rest of OSEES’ expansive catalog. The change is welcome, as the song’s Lovin’ Spoonful-infused keyboard serves as a foil to Dwyer’s crooning about death.

In addition to the webcast airing on April 10th at 8 p.m. ET, OSEES’ Levitation Sessions II will also be available as a live double album. Numerous merchandise packages exist, including a signed poster designed by Dwyer. A portion of the proceeds from the stream and merch sales will go to benefit  Elizabeth House, East LA Women’s Center, St Francis Center, Downtown Women’s Center, and the Hollywood Food Coalition.

While the band’s Levitation Sessions II will have to hold fans over for now, the wait for an in-person OSEES concert will soon be over. On Monday, Red Rocks Amphitheatre announced the band will play a limited capacity show on May 15th. As of now, Red Rocks plans to hold concerts with a 2,500-person capacity, though those precautions are subject to change as state guidelines relax. Tickets to OSEES’ May 15th concert at Red Rocks go on sale on April 9th at 10 a.m. via the venue’s website.
