During the mid Eighties a new instrumental label, Meadowlark Records, signed Richard for his first solo albums, the electronic HEIRBORNE and INNERMISSION. The label also wanted to release his solo, acoustic piano recordings. To reduce confusion about dissimilar projects in the marketplace, the albums...SONGS UNSPOKEN and SECOND STORY, were issued under his middle names- Douglas Trowbridge.
Souther left the Meadowlark label and signed with MCA's Narada Label, releasing two mainstream New Age and World Music projects for them. CROSS CURRENTS, a light jazz ensemble project, featuring the talents of Alex Acuna, Abraham Laboriel, Chester Thompson and Kirk Whalum, released in 1989.
In 1994 Richard received world-wide recognition for is groundbreaking album VISION: The Music Of Hildegard von Bingen, which won the Billboard Classical/Crossover album of the year award. He then followed it up with ILLUMINATION: The Music Of Hildegard von Bingen "The Fire Of The Spirit" for Sony Classical.
