The american trumpet player and composer Hannibal Marvin Peterson was born in Smithville, Texas in 1948. This is his debut album from 1969 (recorded live in Texas at the end of 1968). In Concert (sounds more like studio to me) includes the tribute Groovin For Otis and a cover of James Brown's I Can't Stand It. Musically it's a funky and instrumental soul-jazz album. Groovy!
