“I could listen to Vernon’s solo on that song a million times. It’s scary and strange, but in a good way”: Frank Swart of Funkwrench Blues has recruited Vernon Reid, Oz Noy and Mike Stern to his cosmic cause – but there’s one solo that haunts him

“I make music for weirdos,” says Frank Swart, the San Francisco-based producer-bassist – clearly a master of branding – who since 2017 has been releasing an endless string of wild and wacky instrumental recordings under the moniker Funkwrench Blues.

“If you’re looking for something post-rock, but it’s got a jazz-blues thing and a bit of a cosmic fusion thing, this could appeal to you.” He laughs. “I’ve got over 100,000 listeners on Spotify, so somebody must like it!”
