Indie Exclusive - The Marías' Josh Conway Announces Debut Solo Album plum: Hear "Crumble" Josh Conway, one of the founding members of the Grammy-nominated, TikTok-viral, Stereogum-endorsed group the Marías, is releasing his first solo album. Earlier this year, his bandmate María Zardoya released her own solo project under the name Not For Radio. Conway, the drummer-producer-songwriter, will release his debut solo LP plum in just a few weeks ago. He made the announcement this week with the release of the rubbery single "Crumble." It's effervescent bedroom pop with hypnotic, icy vocals.
