[7] Seattle musicians such as Pearl Jam, Duff McKagan,[8] Alice in Chains,[9] Death Cab for Cutie,[10] and Macklemore voiced their support for preserving the Showbox.

In Fall 2006, the Fenix Underground, a club that spent 15 years in two locations in Pioneer Square, took over the space but just as quickly folded when it filed for bankruptcy in May 2007.

The venue has hosted events featuring My Bloody Valentine, Heart, The Pogues, M.I.A, The Hives, Dropkick Murphys, Josh Ritter, Counting Crows, Panic!

[16] The Showbox SoDo was originally built as a truck warehouse in 1935 for John Eddy Franklin, who was also responsible for the Columbarium at Evergreen Washelli Funeral Home.

Purchased in August 2012,[17] Hansen and Ballmer intended to use the land as part of a proposal for a new sports arena to lure an NBA team back to Seattle following the relocation of the SuperSonics to Oklahoma City in 2008.

[18] After a failed effort to purchase and relocate the Sacramento Kings in 2013, a five-year exclusive agreement with the city on the arena development ended in 2017.
