Both acts made music with nothing but their mouths but, apart perhaps from the choir's vocal arrangements of the music of Moondog, had little in common.
Brought together by last year's multimedia triumph, Whatever Gets You Through the Night, Wounded Knee and Bigg Taj have great chemistry together - and their partly improvised performance inspired by rap, hip-hop, bhangra and Scottish folk gets the crowd going.
"I'm rusty," says Taj, a voice full of apology, as if there was anyone else on earth who could do what he was doing.
Sunday was a day of unusual southside venues. Kinning Park Complex had the feel of an old classroom, especially when Bill Wells cleared his throat to tell the audience that his National Jazz Trio of Scotland was about to begin.
Their music was surprisingly simple, accessible and perfect for an afternoon cross-legged on the floor. With the haunted-house tremolo of Aby Vulliamy's viola layered over the warmth of Wells' simple piano melody, "Ring a Ring o' Roses" finally sounded like a song about the black death.
At the Grand Ole Opry the house lights stayed up a little longer than intended, meaning that the venue's paraphernalia of kitsch Americana started out almost as much a star of the show as "lethargic pop band" eagleowl.
It was an odd setting for a group so incredibly serious, but the swell of the music and the rumble of the drums and Bart Owl's voice, which sounds more like Low with every outing, made distraction fade away.
