In the early 70s, Micael Priest, working through Directions Company, also did work in San Antonio and KEXL radio which was the happening station at the time. Here is the poster for the George Carlin with Kenny Loggins/Jim Messina at Laurie Auditorium. It was weird billing but the show was packed. Laurie was a great venue.
Another killer show was Fleetwood Mac with Pure Prairie League at the Austin Municipal Auditorium. Both of these posters represent some of the best of the early 2 and 3 color posters produced of the period. This was a Concerts Unlimited show.
