Picture yourself in an ancient cathedral, with the dulcet tones of a classical choir resonating as you are bathed in natural light. Talk about transcendent! That’s the vibe at Cloud Tree’s Ambient Music Series, taking guests on a rejuvenating musical journey every Thursday in June. Austin Cantorum kicks off the series with its meditative and illuminating chamber choir music, set against a calming backdrop with gorgeous acoustics. – Kat McNevins
