when did soft machine play at the university of houston?

Soft Machine played in Houston on February 18, 1968 , at the Music Hall as part of a Jimi Hendrix concert lineup. I did not find evidence in the available sources that the venue was the University of Houston, so the best-supported date for a Houston appearance is that February 18, 1968 show.

Quick Scoop

• Date: February 18, 1968.

• City: Houston, Texas.

• Venue in the source: Music Hall, not the University of Houston.

Note on the venue

If you were asking about a specific University of Houston campus event, I’d treat that as a different claim than the Houston Music Hall appearance. The source material available here points to a Houston performance, but not a confirmed University of Houston booking.

TL;DR

The clearest documented Houston date I found for Soft Machine is February 18, 1968 at the Music Hall.
