"In/Out/In, a collection of almost entirely instrumental tracks recorded during Sonic Youth's final decade, would be a crucial record if it was the only thing they ever recorded ... While this collection is certainly no "lost" album due to its decade-long overview and the attention it gives to Sonic Youth's more experimental side, Three Lobed has curated something that feels purposeful. Sonic Youth went out at the end of a 30-year-long career at the top of their game, partially because they never stopped experimenting. In/Out/In proves this fact as if any more proof was necessary".
