Competition for satellite radio listeners is heating up as Sirius continues to enrich their content. Fans of Little Steven VanZant's Underground Garage program, heard Sunday nights in Detroit on WCSX will be drawn to his 24/7 iteration, Sirius' Underground Garage on Channel 25.

We've raved about Pat St. John's outstanding work on Sirius Classic Vinyl (Noon-6 every day on channel 14) and The Vault (6-Midnight weekends on channel 16). Now Pat has added duties as Program Manager on Sirius Blues, channel 29. Hear him there weekdays from 6-Midnight.

This begs the question, is he in the studio seven days a week, six hours a day? Pat tells us that the satellite art is a mixture of live and voice track. Some of his work is pre-recorded to facilitate the schedules of his many on-air guests. But so much of the show is so near to real-time that his programs have the laid back live spontaneity that he trademarked during his many years at WRIF and WPLJ.
