Really beautiful alto trombone playing! Added the following two clips to the 18th Century Timeline of Michael Mulcahy’s solo premiere with the Chicago Symphony, playing Leopold Mozart’s Concerto.

Mulcahy’s alto playing encompasses many of the best elements writers have historically found in the alto trombone (see Alto Quotes): purity (Kastner, 1839); soft brilliancy (William Alexander Barrett, 1879); admirable timbre (Charles Widor, 1904); a certain transparency, even gracility, in general effect; (Horatio Parker 1917); and a lighter, sweeter sound than the tenor (Blatter, 1980).
