 The McGuinn – Hillman – White – Parsons line @-@ up was together for less than a month before Hillman quit to join Gram Parsons in forming the Flying Burrito Brothers . Hillman had become increasingly disenchanted with the Byrds since the South African débâcle and he was also frustrated by business manager Larry Spector 's mishandling of the group 's finances . Things came to a head on September 15 , 1968 , following a band performance at the Rose Bowl stadium in Pasadena , when Hillman and Spector came to blows backstage . In a fit of rage , Hillman threw down his bass in disgust and walked out of the group . Following his exit , Hillman would have a successful career both as a solo artist and with bands such as the Flying Burrito Brothers , Manassas , the Souther – Hillman – Furay Band , and the Desert Rose Band . He remains active , releasing albums and touring , often with ex @-@ Desert Rose Band member Herb Pedersen .
