Hello! For Thirsty, I'd recommend this: https://www.youtube.com/watch?v=7HDfVbGZRms
For their 2nd week of promotions on music shows, aespa actually performed Spicy with live vocals (or less backtrack). This is one I'd recommend: https://www.youtube.com/watch?v=L_yKxGQ5XBo (they also won, so there's an encore where they eat peppers while singing haha)
For WTMW: https://www.youtube.com/watch?v=_plU9O_4Pn8
Other performances I would recommend:
Thirsty and Spicy on It's Live (one take, live band version we never knew we needed): https://www.youtube.com/watch?v=WJMBzYraE7I
Another recent performance was during LOTTE family concert: https://www.youtube.com/watch?v=erCzl8x9Zuo. This includes Black Mamba, Illusion, and Next Level apart from Thirsty + Spicy. The audio isn't perfect and the girls were having in-ear issues, but the live vocals were quite impressive and refreshing, since it's one of the most "live" I've heard them.
They also had amazing performances (rearrangements and solos) during their concerts, only if you're interested!
I'm a new patron and I've enjoyed your aespa and SNSD videos on YT 'cos they're really insightful and fun. <3 Thank you for your reactions!
