Michael Berkeley welcomes US-born jazz trombonist, conductor, composer and educator Scott Stroman , currently head of jazz studies at the Guildhall School of Music and Drama in London. His wide-ranging tastes are reflected in choices that include Duke Ellington, Dizzy Gillespie and Charles Mingus alongside a Bach suite, a Beethoven string quartet, a movement from Haydn's Symphony No 99 and an excerpt from Stravinsky's ballet Apollon Musagète.
